Subject [jira] Created: (HADOOP-5233) Reducer not Succeded after 100%
Date Thu, 12 Feb 2009 10:43:59 GMT
Reducer not Succeded after 100%
-------------------------------

                 Key: HADOOP-5233
                 URL: https://issues.apache.org/jira/browse/HADOOP-5233
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.19.0
            Reporter: Amareshwari Sriramadasu
            Priority: Critical


I have seen a reducer in RUNNING state, when it was waiting for the commitResponse.
Task logs show :
2009-02-12 08:35:36,414 INFO org.apache.hadoop.mapred.TaskRunner: Task:attempt_200902120746_0297_r_000033_0
is done. And is in the process of commiting
and no logs after that.
TT logs say:
2009-02-12 08:35:36,417 INFO org.apache.hadoop.mapred.TaskTracker: Task attempt_200902120746_0297_r_000033_0
is in COMMIT_PENDING
2009-02-12 08:35:36,417 INFO org.apache.hadoop.mapred.TaskTracker: attempt_200902120746_0297_r_000033_0
0.33333334% reduce > sort

This looks like, the task progress went from COMMIT_PENDING to RUNNING again.
