Date Wed, 11 Nov 2015 09:58:10 GMT
Ufuk Celebi created FLINK-3000:
----------------------------------

             Summary: Add ShutdownHook to YARN CLI to prevent lingering sessions
                 Key: FLINK-3000
                 URL: https://issues.apache.org/jira/browse/FLINK-3000
             Project: Flink
          Issue Type: Bug
          Components: YARN Client
    Affects Versions: 0.10
            Reporter: Ufuk Celebi
             Fix For: 0.10.1


Submitting a job via
{code}
bin/flink run -m yarn-cluster ...
{code}
and terminating the client can lead to lingering YARN sessions allocating cluster resources.

This was reported by a user.

{code}
1) One starts a flink job in the yarn mode
2) He sees that containers are not allocated since cluster is busy
3) Presses Ctrl+C
4) An “empty” flink session remains in the cluster although the Flink didn’t print that
“you can track your application on the X URL”
{code}
