------------------------------------

             Summary: Check that the GlobalBufferPool has all buffers available after a task crashed with an exception
                 Key: FLINK-1099
                 URL: https://issues.apache.org/jira/browse/FLINK-1099
             Project: Flink
          Issue Type: Test
            Reporter: Till Rohrmann
            Assignee: Ufuk Celebi
            Priority: Minor


[~StephanEwen] noticed that not all buffers are returned to the GlobalBufferPool in case of an exception in a job. He already fixed the problem and also introduced assertions in the JobManagerITCase to check this. Due to the incorporation of the actor model this information is no longer available in the context of an JobManager integration test. Furthermore, I think that the JobManagerITCase is not the right place to check for these low level functionalities. Therefore, I propose to write an explicit test at the level of the RuntimeEnvironment to check the correct behaviour of releasing allocated resources.
