John Sichi commented on HIVE-1130:
----------------------------------
You'll need to dig into the logs to diagnose the problem.
I noticed this in the end of the last .q.out you uploaded.
+PREHOOK: Output:
file:/tmp/nhuyn/hive_2010-08-30_13-07-04_657_9209893909733875962/-mr-10000
+FAILED: Execution Error, return code 2 from
org.apache.hadoop.hive.ql.exec.MapRedTask
Is that the failure you are getting when you run with ant test?
If so, you can find more info in one of the exec logs, probably in /tmp/nhuyn.
