> 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.
