Log job history events to a common dump file
--------------------------------------------
Key: HADOOP-5846
URL: https://issues.apache.org/jira/browse/HADOOP-5846
Project: Hadoop Core
Issue Type: New Feature
Components: mapred
Reporter: Amar Kamat
Assignee: Amar Kamat
As of today all the jobhistory events are logged to separate files. It would be
nice to also dump all this info into a common file so that external tools (e.g
Chukwa) can harvest history info. Job configuration should also be dumped.
Whether to use a same log file for history dumps and configuration dumps should
be configurable (by default everything goes to one file).
