> Key: MAPREDUCE-2717
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2717

> Issue Type: Improvement
> Components: mrv2

> Fix For: 0.23.0

> Today if an AM crashes, we have to dig through logs - very cumbersome. It is good to have client print some reason for
> AM crash. Various possible reasons for AM crash:
> (1) AM container failed during localization itself.
> (2) AM container launched but failed before properly starting, for e.g. due to classpath issues
> (3) AM failed after starting properly.
> (4) an AM is expired and killed by the RM
> Potential fixes:
> - For (1) and (2) the client should obtain the container-status, container diagnostics and exit code.
> - For (3), the AM should set some kind of reason for failure during its heartbeat to RM and the client should obtain
> the same from RM.
