                 Key: MAPREDUCE-697
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-697
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: tasktracker
    Affects Versions: 0.20.1
            Reporter: Suman Sehgal
            Priority: Critical


Jobwise list of blacklisted tasktrackers doesn't get refreshed even after restarting blacklisted tasktrackers. "jobdetails.jsp" page keeps on showing the same no. of blacklisted tasktrackers (it doesn't get back to zero).

One associated issue:
=================
--> More than 25% of TTs are blacklisted in a job.
--> Restart the blacklisted TTs. All the tasktrackers are healthy now.
--> try to blacklist other TT for the same job.

Not able to blacklist the "other" tasktracker even if  "mapred.max.tracker.failures" exceeds the specified limit.
