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.
