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

             Summary: Requesting non-existing log/stdout file from TM crashes the it
                 Key: FLINK-5470
                 URL: https://issues.apache.org/jira/browse/FLINK-5470
             Project: Flink
          Issue Type: Bug
          Components: TaskManager
    Affects Versions: 1.2.0, 1.3.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
            Priority: Critical
             Fix For: 1.2.0, 1.3.0


Requesting the TM log/stdout file via the web interface crashes the TM if the respective file does not exist. This is, for example, the case when running Flink via DC/OS.
