@InterfaceAudience.Public @InterfaceStability.Unstable public abstract int getExitStatus()
Get the exit status for the container.
Note: This is valid only for completed containers i.e. containers
with state ContainerState.COMPLETE
.
Otherwise, it returns an ContainerExitStatus.INVALID.
Containers killed by the framework, either due to being released by the application or being 'lost' due to node failures etc. have a special exit code of ContainerExitStatus.ABORTED.
When threshold number of the nodemanager-local-directories or threshold number of the nodemanager-log-directories become bad, then container is not launched and is exited with ContainersExitStatus.DISKS_FAILED.
