HDFS-14350:dfs.datanode.ec.reconstruction.threads not take effect by hunshenshi · Pull Request #582 · apache/hadoop

hunshenshi · 2019-03-09T05:42:31Z

In ErasureCodingWorker, stripedReconstructionPool is create by

initializeStripedBlkReconstructionThreadPool(conf.getInt(
DFSConfigKeys.DFS_DN_EC_RECONSTRUCTION_THREADS_KEY,
DFSConfigKeys.DFS_DN_EC_RECONSTRUCTION_THREADS_DEFAULT));
privatevoidinitializeStripedBlkReconstructionThreadPool(intnumThreads) {
LOG.debug("Using striped block reconstruction; pool threads={}",
numThreads);
stripedReconstructionPool = DFSUtilClient.getThreadPoolExecutor(2,
numThreads, 60, newLinkedBlockingQueue<>(),
"StripedBlockReconstruction-", false);
stripedReconstructionPool.allowCoreThreadTimeOut(true);
}

so stripedReconstructionPool is a ThreadPoolExecutor, and the queue is a LinkedBlockingQueue, then the active thread is awalys 2, the dfs.datanode.ec.reconstruction.threads not take effect.

jojochuang · 2019-08-17T00:15:09Z

I am not sure this is the right fix -- reading at the code, clients keeps 2 threads even during idle, and dfs.datanode.ec.reconstruction.threads specifies the max number of threads. That looks reasonable.
Perhaps all we should do is to update the description of the configuration key in hdfs-default.xml.

hunshenshi · 2019-08-18T03:23:29Z

hi, @jojochuang Thanks for review.
The queue of ThreadPoolExecutor is a LinkedBlockingQueue, the queue will not be filled, so the max num will not take effect. So I think the active thread is awalys 2, dfs.datanode.ec.reconstruction.threads not take effect.
