> Use BlockingThreadPoolExecutorService for nnProbingThreadPool in
> ObserverReadProxy
> ----------------------------------------------------------------------------------
>
> Key: HDFS-17067
> URL: https://issues.apache.org/jira/browse/HDFS-17067
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs
> Affects Versions: 3.4.0
> Reporter: Xing Lin
> Assignee: Xing Lin
> Priority: Major
> Labels: pull-request-available
>
> In HDFS-17030, we introduced an ExecutorService, to submit
> getHAServiceState() requests. We constructed the ExecutorService directly
> from a basic ThreadPoolExecutor, without setting _allowCoreThreadTimeOut_ to
> true. Then, the core thread will be kept up and running even when the main
> thread exits. To fix it, one could set _allowCoreThreadTimeOut_ to true.
> However, in this PR, we decide to directly use an existing executorService
> implementation (_BlockingThreadPoolExecutorService_) in hadoop instead. It
> takes care of setting _allowCoreThreadTimeOut_ and also allows setting the
> prefix for thread names.
> {code:java}
> private final ExecutorService nnProbingThreadPool =
> new ThreadPoolExecutor(1, 4, 1L, TimeUnit.MINUTES,
> new ArrayBlockingQueue<Runnable>(1024));
> {code}
> A second minor issue is we did not shutdown the executorService in close().
> It is a minor issue as close() will only be called when the garbage collector
> starts to reclaim an ObserverReadProxyProvider object, not when there is no
> reference to the ObserverReadProxyProvider object. The time between when an
> ObserverReadProxyProvider becomes dereferenced and when the garage collector
> actually starts to reclaim that object is out of control/under-defined
> (unless the program is shutdown with an explicit System.exit(1)).
