[jira] [Created] (FLINK-2221) Checkpoints to "file://" are not cleaned up

Aljoscha Krettek created FLINK-2221:
---------------------------------------

             Summary: Checkpoints to "file://" are not cleaned up
                 Key: FLINK-2221
                 URL: https://issues.apache.org/jira/browse/FLINK-2221
             Project: Flink
          Issue Type: Bug
          Components: Streaming
            Reporter: Aljoscha Krettek


If you think about it, this could never work. The state handle cleanup logic happens purely on the JobManager. So what happens is that the TaskManagers create state in some directory, let's say /tmp/checkpoints, on the TaskManager. For cleanup, the JobManager gets the state handle and calls discard (on the JobManager), this tries to cleanup the state in /tmp/checkpoints, but of course, there is nothing there since we are still on the JobManager.
