[jira] [Commented] (TEZ-1141) DAGStatus.Progress should include number of failed attempts

    [ https://issues.apache.org/jira/browse/TEZ-1141?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14175874#comment-14175874 ] 

Gopal V commented on TEZ-1141:
------------------------------

LGTM, I found that this doesn't track NM blacklisting, but that is a completely different problem.

I've updated patch on HIVE-7838 to use this and it is useful, to narrow down query failures (particularly reducer OOMs happening).

> Currently its impossible to know whether a job is seeing a lot of issues and failures because we only report running tasks. Eventually the job fails but before that we have no indication that a bunch of task failures have been happening.
