Subject [jira] [Created] (MAPREDUCE-6362) History Plugin should be updated
Date Mon, 11 May 2015 18:28:00 GMT
Mit Desai created MAPREDUCE-6362:

             Summary: History Plugin should be updated
                 Key: MAPREDUCE-6362
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6362
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 2.6.1
            Reporter: Mit Desai

As applications complete, the RM tracks their IDs in a completed list. This list is routinely
truncated to limit the total number of application remembered by the RM.

When a user clicks the History for a job, either the browser is redirected to the application's
tracking link obtained from the stored application instance. But when the application has
been purged from the RM, an error is displayed.

In very busy clusters the rate at which applications complete can cause applications to be
purged from the RM's internal list within hours, which breaks the proxy URLs users have saved
for their jobs.

We would like the RM to provide valid tracking links persist so that users are not frustrated
by broken links.
