[jira] [Commented] (TEZ-4230) LocalContainerLauncher can kill task future too early, causing app hang

["László Bodor (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TEZ-4230?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17191554#comment-17191554 ] 

László Bodor commented on TEZ-4230:
-----------------------------------

[~jeagles], [~jlowe]: could you please review this small patch? this is probably the last 0.10.0 blocker

long story short, I identified this with a flaky hive test, analyzed the logs, and with the fix, the test passed 500 times without an issue (details in previous comment)

> Reproduced issue in ptest run which I made to run against tez staging artifacts (https://repository.apache.org/content/repositories/orgapachetez-1068/)

> I'm about to investigate this. I think Tez 0.10.0 cannot be released until we won't confirm if it's a hive or tez bug.
