Subject [jira] [Commented] (YARN-1541) Invalidate AM Host/Port when app attempt is done so that in the mean-while client doesn’t get wrong information.

    [ https://issues.apache.org/jira/browse/YARN-1541?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13857695#comment-13857695

Vinod Kumar Vavilapalli commented on YARN-1541:
-----------------------------------------------

It's interesting to realize via the test that we are invalidating host/port information for
finished apps. We shouldn't perhaps be doing that for succeeded apps? Apps may use this similar
to final-tracking URL after YARN-1225.

In addition one more place where this invalidation is really helpful is when an AM crashed
or expired and client doesn't get the same address while the RM is in the process of launching
a new AM. Can you add a test for that?
