[jira] [Updated] (TEZ-1682) Tez AM hangs at times when there are task failures

["Siddharth Seth (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TEZ-1682?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Siddharth Seth updated TEZ-1682:
--------------------------------
    Attachment: TEZ-1682.1.txt

Fairly straight forward patch. 
task.taskAttemptStatus.clear() on a KillRequest seems incorrect - since it's used to keep track of completed events.

Added a test to verify the Task state change.

[~hitesh], [~zjffdu] - please review - keeping in mind that multiple Finished events should not be generated.

> Reported by [~karams]. 
> The Task does not move into it's final state, and effectively does not send the relevant events to the Vertex.
> Happens when there's multiple attempts for the task - caused by Node failure for instance.
