Subject [jira] [Commented] (STREAMS-80) StreamsProcressorTask and StreamsPersistWriterTask are BROKEN
Date Mon, 19 May 2014 17:16:38 GMT

ASF GitHub Bot commented on STREAMS-80:
---------------------------------------

Github user smashew commented on the pull request:

    Essentially, once the provider is terminated the hose is 'shut off' and all the remaining
queues deplete until they are satisfied, however long that takes.

> A recent commit seems to have introduced this.  Its a simple fix, but the while statement
on line 70 of StreamsProviderTask should read
> while(this.keepRunning.get() || datum != null) {
> And line 75 in StreamsPersist writer task should read
> while(this.keepRunning.get() || datum != null) {
> Both lines are missing the datum != null statement.  This causes tasks to be shutdown
before data is processed and data is orphaned in the stream.  In the worst case only the provider
runs.
