JobTracker should assign unique jobids across restarts
-------------------------------------------------------
Key: HADOOP-471
URL: http://issues.apache.org/jira/browse/HADOOP-471
Project: Hadoop
Issue Type: Improvement
Components: mapred
Reporter: Sanjay Dahiya
Priority: Minor
JobTracker assigns jobids starting from _001 every time it restarts. It should
not reuse Ids for a large number of jobs ( 10,000 ?) even if it is restarted.
It will make it easy to track and analyze jobs in history by jobids .
