[jira] [Created] (MAPREDUCE-4302) NM goes down if error encountered during log aggregation

Daryn Sharp created MAPREDUCE-4302:
--------------------------------------

             Summary: NM goes down if error encountered during log aggregation
                 Key: MAPREDUCE-4302
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4302
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.0.0-alpha, 0.23.0, trunk
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp
            Priority: Critical


When a container launch request is sent to the NM, if _any_ exception occurs during the init of log aggregation then the NM goes down.  The problem can be induced by situations including, but certainly not limited to: transient rpc connection issues, missing tokens, expired tokens, permissions, full/quota exceeded dfs, etc.  The problem may occur with and without security enabled.

The ramification is an entire cluster can be rather easily brought down either maliciously, accidentally, or via a submission bug.
