> 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.
