[jira] [Commented] (TEZ-1625) TestVertexImpl occasionally hangs

    [ https://issues.apache.org/jira/browse/TEZ-1625?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14176622#comment-14176622 ] 

Jeff Zhang commented on TEZ-1625:
---------------------------------

The root cause is that DrainDispatcher may been created 2 times, and there's an AsyncDispatcherThread in DrainDispatcher, we should stop DrainDispatcher before creating another DrainDispatcher, otherwise we may get 2 AsyncDispatcherThread. Even we stop DrainDispatcher in tearDown there's still one AsyncDispatcherThread live there.

[~bikassaha] Please help review it.
