> In some cases, container launch may fail but container will not be properly
> returned to RM.
> This could happen when AM trying to prepare container launch context but
> failed w/o sending container launch context to NM (Once container launch
> context is sent to NM, NM will report failed container to RM).
> Exception like:
> {code:java}
> java.io.FileNotFoundException: File does not exist:
> hdfs://ns1/user/wtan/.yarn/services/tf-job-001/components/1531852429056/primary-worker/primary-worker-0/run-PRIMARY_WORKER.sh

> And even after container launch context prepare failed, AM still trying to
> monitor container's readiness:

> presence", exception="java.io.IOException: primary-worker-0: IP is not
> available yet"
