--------------------------------------
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.
