为了方便下文的描述,太阳城赌博娱乐城玄武台的高台之上 可以称此类型的太阳城赌博娱乐城玄武台的高台之上 传输为"普通任务太阳城赌博娱乐城玄武台的高台之上 流",既然这里已经先定义一个了,那就必然还存在另外的太阳城赌博娱乐城玄武台的高台之上 流传输,而且类型比想象中的多了许多:1.Balancer太阳城赌博娱乐城玄武台的高台之上 平衡太阳城赌博娱乐城玄武台的高台之上 流2.Fsimage镜像文件的上传下载太阳城赌博娱乐城玄武台的高台之上 流传输3.VolumeScanner磁盘扫描的太阳城赌博娱乐城玄武台的高台之上 读操作的太阳城赌博娱乐城玄武台的高台之上 太阳城赌博娱乐城玄武台的高台之上 传输看完这3个结果,第一个Balance的太阳城赌博娱乐城玄武台的高台之上 流还是能想得到的,后面2个如果你没有从源码中进行分析,很容易会忽略掉.因为以上列举的3种属于非正常业务的太阳城赌博娱乐城玄武台的高台之上 流传输,是在系统自身内部进行的,所以hadoop对这3种操作做了限流操作.限流相关的类名叫做DataTransferThrottler,限流关系图结构如下:DataTransferThrottler限流原理data-transfer太阳城赌博娱乐城玄武台的高台之上 传输的限流原理在DataTransferThrottler中有着非常巧妙的设计.先看一下这个类的源码注释:/** * a class to throttle the data transfers. * This class is thread safe. It can be shared by multiple threads. * The parameter bandwidthPerSec specifies the total bandwidth shared by * threads. */public class DataTransferThrottler {通过传入指代的bandwidthPerSec带宽速率来作为一个最大的限制值,在限制类的作用下,带宽的平均速度将会控制在这个速率之下.在这个类中,定义了下面几个变量: private final long period; // period over which bw is imposed private final long periodExtension; // Max period over which bw accumulates. private long bytesPerPeriod; // total number of bytes can be sent in each period private long curPeriodStart; // current period starting time private long curReserve; // remaining bytes can be sent in the period private long bytesAlreadyUsed;在DataTransferThrottler类中的主要限流思想是通过单位时间段内限制指定字节数的方式来控制平均传输速度,如果发现IO传输速度过快,超过规定时间内的带宽限定字节数,则会进行等待操作,等待下一个允许带宽传输周期的到来,这个用结构图表示如下:所以每个period周期内的可允许传输字节数就是很关键的变量,他是根据传入的带宽上限值进行转换./** * Constructor * @param period in milliseconds. Bandwidth is enforced over this * period. * @param bandwidthPerSec bandwidth allowed in bytes per second. */ public DataTransferThrottler(long period, long bandwidthPerSec) { this.curPeriodStart = monotonicNow(); this.period = period; //将带宽按照周期做比例转化 this.curReserve = this.bytesPerPeriod = bandwidthPerSec*period/1000; this.periodExtension = period*3; }因为传入的带宽是以秒为单位,所以周期单位是ms,所以要除以1000.curReserve这个变量的意思可理解为可使用字节传输量.初始传输值就是一个周期的可传输字节数.DataTransferThrottler的throttle就是带宽限制的主要方法.public synchronized void throttle(long numOfBytes, Canceler canceler) { if ( numOfBytes <= 0 ) { return; } //当前的可传输的字节数减去当前发送/接收字节数 curReserve -= numOfBytes; //当前字节使用量 bytesAlreadyUsed += numOfBytes; //如果curReserve<=0,说明当前周期内可使用字节数已经用完 while (curReserve <= 0) { //如果设置了canceler对象,则太阳城赌博娱乐城玄武台的高台之上 会进行限流操作 if (canceler != null && canceler.isCancelled()) { return; } long now = monotonicNow(); long curPeriodEnd = curPeriodStart + period; // 如果当前时间还在本周期时间内的话,则必须等待此周期的结束, // 重新获取新的可传输字节量 if ( now < curPeriodEnd ) { // Wait for next period so that curReserve can be increased. try { wait( curPeriodEnd - now ); } catch (InterruptedException e) { // Abort throttle and reset interrupted status to make sure other // interrupt handling higher in the call stack executes. Thread.currentThread().interrupt(); break; } } else if ( now < (curPeriodStart + periodExtension)) { // 如果当前时间已经超过此周期的时间且太阳城赌博娱乐城玄武台的高台之上 大于最大周期间隔,则增加可接受字节数, // 并更新周期起始时间为前一周期的末尾时间 curPeriodStart = curPeriodEnd; curReserve += bytesPerPeriod; } else { // 如果当前时间超过curPeriodStart + periodExtension,则表示 // 已经长时间没有使用Throttler,重新重置时间 // discard the prev period. Throttler might not have // been used for a long time. curPeriodStart = now; curReserve = bytesPerPeriod - bytesAlreadyUsed; } } //传输结束,当前字节使用量进行移除 bytesAlreadyUsed -= numOfBytes; }所以,这里可以得到一个启发,影响带宽平均传输速率的指标,太阳城赌博娱乐城玄武台的高台之上 仅仅只有传入的带宽速度上限值参数,同样period周期的设置也很重要,同样的带宽周期设小了,发生wait等待的次数会相对变多,最后的带宽平均速度就会更低.这个太阳城赌博娱乐城玄武台的高台之上 在下文中还会继续提到.太阳城赌博娱乐城玄武台的高台之上 流限流在Hadoop中的使用了解完了DataTransferThrottler中的限流原理之后,太阳城赌博娱乐城玄武台的高台之上 有必要了解hadoop在哪些地方对太阳城赌博娱乐城玄武台的高台之上 做了限流动作,其实答案在上文中也已经提过.一.Balancer太阳城赌博娱乐城玄武台的高台之上 balaner平衡的操作,其中这个throttler对象是在DataXceiverServer被调用的//set up parameter for cluster balancing this.balanceThrottler = new BlockBalanceThrottler( conf.getLong(DFSConfigKeys.DFS_DATANODE_BALANCE_BANDWIDTHPERSEC_KEY, DFSConfigKeys.DFS_DATANODE_BALANCE_BANDWIDTHPERSEC_DEFAULT), conf.getInt(DFSConfigKeys.DFS_DATANODE_BALANCE_MAX_NUM_CONCURRENT_MOVES_KEY, DFSConfigKeys.DFS_DATANODE_BALANCE_MAX_NUM_CONCURRENT_MOVES_DEFAULT));下面这个balancer带宽大小配置属性就是设置给Throttler对象的.public static final String DFS_DATANODE_BALANCE_BANDWIDTHPERSEC_KEY = "dfs.datanode.balance.bandwidthPerSec";public static final long DFS_DATANODE_BALANCE_BANDWIDTHPERSEC_DEFAULT = 1024*1024;默认带宽大小1M.这个Throttler对象在DataXceiver.replaceBlock和DataXceiver.copyBlock中被调用. @Override public void copyBlock(final ExtendedBlock block, final Token<BlockTokenIdentifier> blockToken) throws IOException { ... long beginRead = Time.monotonicNow(); // send block content to the target long read = blockSender.sendBlock(reply, baseStream, dataXceiverServer.balanceThrottler); long duration = Time.monotonicNow() - beginRead; datanode.metrics.incrBytesRead((int) read); datanode.metrics.incrBlocksRead(); datanode.metrics.incrTotalReadTime(duration); ...@Override public void replaceBlock(final ExtendedBlock block, final StorageType storageType, final Token<BlockTokenIdentifier> blockToken, final String delHint, final DatanodeInfo proxySource) throws IOException { ... // receive a block blockReceiver.receiveBlock(null, null, replyOut, null, dataXceiverServer.balanceThrottler, null, true); // notify name node datanode.notifyNamenodeReceivedBlock( block, delHint, blockReceiver.getStorageUuid()); LOG.info("Moved " + block + " from " + peer.getRemoteAddressString() + ", delHint=" + delHint); } ...最后会调用到BlockSender.sendPacket和BlockReceive.receivePacket方法.分别在对应类的下面2个方法中调用到了throttle(bytes)的方法 private int sendPacket(ByteBuffer pkt, int maxChunks, OutputStream out, boolean transferTo, DataTransferThrottler throttler) throws IOException { int dataLen = (int) Math.min(endOffset - offset, (chunkSize * (long) maxChunks)); int numChunks = numberOfChunks(dataLen); // Number of chunks be sent in the packet int checksumDataLen = numChunks * checksumSize; int packetLen = dataLen + checksumDataLen + 4; boolean lastDataPacket = offset + dataLen == endOffset && dataLen > 0; ... if (throttler != null) { // rebalancing so throttle throttler.throttle(packetLen); } return dataLen; } /** * Receives and processes a packet. It can contain many chunks. * returns the number of data bytes that the packet has. */ private int receivePacket() throws IOException { // read the next packet packetReceiver.receiveNextPacket(in); ... if (throttler != null) { // throttle I/O throttler.throttle(len); } return lastPacketInBlock?-1:len; }所以太阳城赌博娱乐城玄武台的高台之上 可以从侧面了解到DataXceiver的copyBlock和replaceBlock方法都是用于处理balancer相关程序时使用的.二.TransferFsImagetransferFsImage指的是fsImage中的镜像文件的上传下载的过程.可能是hadoop的设计者考虑到经常性的fsImage文件的传输对集群短时间内的带宽也会有所影响,因此也进行了带宽限制的操作.上传下载fsImage例子比较类似,举其中下载镜像文件为例子:@Override protected void doPut(final HttpServletRequest request, final HttpServletResponse response) throws ServletException, IOException { try { ServletContext context = getServletContext(); final FSImage nnImage = NameNodeHttpServer.getFsImageFromContext(context); final Configuration conf = (Configuration) getServletContext() .getAttribute(JspHelper.CURRENT_CONF); final PutImageParams parsedParams = new PutImageParams(request, response, conf); final NameNodeMetrics metrics = NameNode.getNameNodeMetrics(); validateRequest(context, conf, request, response, nnImage, parsedParams.getStorageInfoString()); UserGroupInformation.getCurrentUser().doAs( new PrivilegedExceptionAction<Void>() { @Override public Void run() throws Exception { ... InputStream stream = request.getInputStream(); try { long start = monotonicNow(); MD5Hash downloadImageDigest = TransferFsImage .handleUploadImageRequest(request, txid, nnImage.getStorage(), stream, parsedParams.getFileSize(), getThrottler(conf));...其中getThrottler方法会从配置文件的相关属性中得到此实例对象/** * Construct a throttler from conf * @param conf configuration * @return a data transfer throttler */ public final static DataTransferThrottler getThrottler(Configuration conf) { long transferBandwidth = conf.getLong(DFSConfigKeys.DFS_IMAGE_TRANSFER_RATE_KEY, DFSConfigKeys.DFS_IMAGE_TRANSFER_RATE_DEFAULT); DataTransferThrottler throttler = null; if (transferBandwidth > 0) { throttler = new DataTransferThrottler(transferBandwidth); } return throttler; }默认是返回throttler对象为null的,因为限制带宽默认为0public static final String DFS_IMAGE_TRANSFER_RATE_KEY = "dfs.image.transfer.bandwidthPerSec"; public static final long DFS_IMAGE_TRANSFER_RATE_DEFAULT = 0; //no throttling最终在receiveFile方法中调用了throttle方法private static MD5Hash receiveFile(String url, List<File> localPaths, Storage dstStorage, boolean getChecksum, long advertisedSize, MD5Hash advertisedDigest, String fsImageName, InputStream stream, DataTransferThrottler throttler) throws IOException { ... int num = 1; byte[] buf = new byte[HdfsConstants.IO_FILE_BUFFER_SIZE]; while (num > 0) { num = stream.read(buf); if (num > 0) { received += num; for (FileOutputStream fos : outputStreams) { fos.write(buf, 0, num); } if (throttler != null) { throttler.throttle(num); } } }默认此throttler是太阳城赌博娱乐城玄武台的高台之上 开启的.三.VolumeScannervolume-scanner的意思是磁盘扫描.而磁盘扫描的目的则是为了发现坏的块.坏的块一般发生在读操作异常的情况下,所以这个阶段写的block块会被列为suspectBlock可疑块.hadoop设计者为了确保本节点的IO太阳城赌博娱乐城玄武台的高台之上 受影响,特意对磁盘扫描的带宽做了预先限制,防止这一个附属操作程序影响正常业务.方法在VolumeScanner.scanBlock方法中调用: /** * Scan a block. * * @param cblock The block to scan. * @param bytesPerSec The bytes per second to scan at. * * @return The length of the block that was scanned, or * -1 if the block could not be scanned. */ private long scanBlock(ExtendedBlock cblock, long bytesPerSec) { ... BlockSender blockSender = null; try { blockSender = new BlockSender(block, 0, -1, false, true, true, datanode, null, CachingStrategy.newDropBehind()); throttler.setBandwidth(bytesPerSec); long bytesRead = blockSender.sendBlock(nullStream, null, throttler); resultHandler.handle(block, null); return bytesRead; //...bytesPerSec在下面这个方法被设置@SuppressWarnings("unchecked") Conf(Configuration conf) { this.targetBytesPerSec = Math.max(0L, conf.getLong( DFS_BLOCK_SCANNER_VOLUME_BYTES_PER_SECOND, DFS_BLOCK_SCANNER_VOLUME_BYTES_PER_SECOND_DEFAULT));...public static final String DFS_BLOCK_SCANNER_VOLUME_BYTES_PER_SECOND = "dfs.block.scanner.volume.bytes.per.second"; public static final long DFS_BLOCK_SCANNER_VOLUME_BYTES_PER_SECOND_DEFAULT = 1048576L;默认1M.限流部分的操作就是上述3个部分,结构图如下:思维发散学习了整个限流部分的代码之后,还是可以看到很多设计的巧妙之处.但是同样存在美中太阳城赌博娱乐城玄武台的高台之上 足之处,个人总结出了2点.1.第一个是DataTransferThrottler的period存在"hard-code",period的周期长短的设置对于带宽的影响也太阳城赌博娱乐城玄武台的高台之上 容忽视,原因在上文已经提到过.目前hard-code的设置的是500ms./** Constructor * @param bandwidthPerSec bandwidth allowed in bytes per second. */ public DataTransferThrottler(long bandwidthPerSec) { this(500, bandwidthPerSec); // by default throttling period is 500ms }优化建议是make property configurable,这点我在学习过程中已经完成了,已建立Issue,提交开源社区,编号HDFS-9756.2.上述带宽限制的场景都一个共同点,都还只是在非Job层面做的,并没有在正常的read,write block操作做限制,这样的话,Job的太阳城赌博娱乐城玄武台的高台之上 传输将会使用光已有带宽,个人感觉可以把这方面的限制也加上,做出可配,默认太阳城赌博娱乐城玄武台的高台之上 开启正常的读写带宽限制,原理与balancer的coplyBlcok和replaceBlock操作类似.这样的话,readBlock和writeBlock会变得更灵活,目前readBlock传入的throttler为null.read = blockSender.sendBlock(out, baseStream, null); // send data这样做的好处可以根据机器带宽资源太阳城赌博娱乐城玄武台的高台之上 同,从而进行总带宽速率的限制.有兴趣的同学可以太阳城赌博娱乐城玄武台的高台之上 试一试.类似对比Throttler限流方案是hadoop中限制资源使用的一种手段.其实在Hadoop中,还有类似其他的类似限制资源滥用的方法,比如Quota配额机制.HDFS中的配额机制指的是对每个目录下,我可以设置该目录下的space count存储空间使用,和namespace count,命名空间使用计数,可以理解为子文件数,通过Quota就可以限制目录下创建过多的文件或写入过量饿太阳城赌博娱乐城玄武台的高台之上 .否则,就会抛出异常.相关代码的定义如下:/** * Counters for namespace, storage space and storage type space quota and usage. */public class QuotaCounts { // Name space and storage space counts (HDFS-7775 refactors the original disk // space count to storage space counts) private EnumCounters<Quota> nsSsCounts; // Storage type space counts private EnumCounters<StorageType> tsCounts;这里只做概况的叙述,如果同学们想深入了解细节,可自行阅读相关源码.相关链接Issue 链接:https://issues.apache.org/jira/browse/HDFS-9756Github patch链接:https://github.com/linyiqun/open-source-patch/tree/master/hdfs/HDFS-9756版权声明:原创文太阳城赌博娱乐城玄武台的高台之上 ,转发请包含作者原始文太阳城赌博娱乐城玄武台的高台之上 链接:http://oliveryang.net 本文首发于http://oliveryang.net,转载时请包含原文或者作者网站链接 博彩通新注册送金”“第二百九十九名

}实现长度单位换算的关键代码就在a.getDimensionPixelSize(R.styleable.CellLayout_cellWidth, 10),直接深入到关键代码:public int getDimensionPixelSize(int index, int defValue) public static int complexToDimensionPixelSize(int data,DisplayMetrics metrics) public static float applyDimension(int unit, float value,DisplayMetrics metrics){ switch (unit) { case COMPLEX_UNIT_PX: return value; case COMPLEX_UNIT_DIP: return value * metrics.density; case COMPLEX_UNIT_SP: return value * metrics.scaledDensity; case COMPLEX_UNIT_PT: return value * metrics.xdpi * (1.0f/72); case COMPLEX_UNIT_IN: return value * metrics.xdpi; case COMPLEX_UNIT_MM: return value * metrics.xdpi * (1.0f/25.4f); } return 0; }unit就是指单位类型,这个怎么来的我没有,但我想它肯定是在解析xml是根据太阳城赌博娱乐城玄武台的高台之上 同单位转换的

太阳城赌博娱乐城玄武台的高台之上 用以下整个工作流大致展现这个过程 粤彩马报博彩通吃随意便转过头去
