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?
> Invalidate AM Host/Port when app attempt is done so that in the mean-while
> client doesn’t get wrong information.
