Subject DiskChecker$DiskErrorException
Date Wed, 02 Mar 2011 06:39:51 GMT
Hi,

I receives below messages when I trying to run SampleUploader,

TaskTracer:

2011-03-02 15:31:03,040 INFO org.apache.hadoop.mapred.TaskTracker:
org.apache.hadoop.util.DiskChecker$DiskErrorException: Could not find
taskTracker/jobcache/job_201103021520_0005/attempt_201103021520_0005_m_000004_0/output/file.out
in any of the configured local directories

2011-03-02 15:31:06,049 DEBUG org.apache.hadoop.mapred.TaskTracker:

HBase doesn't throws any error but, Job is always 99%.

11/03/02 15:38:29 INFO mapred.JobClient:  map 99% reduce 0%

I ran this on one whole rack 16 nodes, 256 cores, 50G memory.

Any advice?
