Subject Exception: "Can not get the relative path..."
Date Sat, 16 Jan 2010 23:20:00 GMT
Hey guys,

I'm getting an exception I haven't seen before. I'm running hadoop in
single-node mode for some dev work. Tasktracker log gives me this:

java.io.IOException: Can not get the relative path: base =
hdfs://localhost:8020/user/bradfordstephens/queueout/_temporary/_attempt_201001152019_0004_m_000000_0
child = hdfs://localhost/user/bradfordstephens/queueout/_temporary/_attempt_201001152019_0004_m_000000_0/part-m-00000
	at org.apache.hadoop.mapreduce.lib.output.FileOutputCommitter.getFinalPath(FileOutputCommitter.java:200)

etc...

Around the same time, I see this in the tasktracker log:

2010-01-15 20:24:25,190 INFO org.apache.hadoop.mapred.TaskTracker:
org.apache.hadoop.util.DiskChecker$DiskErrorException: Could not find
taskTracker/jobcache/job_201001152019_0004/attempt_201001152019_0004_m_000001_0/output/file.out
in any of the configured local directories

I've got a gut feeling this may be a config issue, but not sure where...

Cheers,
Bradford
