Description
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.
