Chang Li commented on MAPREDUCE-5003:
-------------------------------------
The broken unit test is unrelated to my change. Have test this test on my local
machine with my patch on and the test passed. [~jlowe] please help review the
latest patch. Thanks!
> AM recovery should recreate records for attempts that were incomplete

> As discussed in MAPREDUCE-4992, it would be nice if the AM recovered task
> attempt entries for *all* task attempts launched by the prior app attempt
> even if those task attempts did not complete. The attempts would have to be
> marked as killed or something similar to indicate it is no longer running.
> Having records for the task attempts enables the user to see what nodes were
> associated with the attempts and potentially access their logs.
