The hadoop is 0.19-trunk checked out 2008-10-10 we use this trunck and after run several days, it will alway hangs several reducers when copying at 0.0%。
the log is always like this: 2009-01-09 11:19:38,600 INFO org.apache.hadoop.mapred.TaskTracker: attempt_200901081900_0015_r_000000_3 0.0% reduce > copy > 2009-01-09 11:19:41,331 INFO org.apache.hadoop.mapred.TaskTracker: org.apache.hadoop.util.DiskChecker$DiskErrorException: Could not find taskTracker/jobcache/job_200901081900_0015/attempt_200901081900_0015_r_000000_3/output/file.out in any of the configured local directories I also wonder why it find the reduce output in the local directories? I just know the mapresult is on local disk. -- Best wishes! My Friend~
