We have hive query processing zipped csv files. the query was scanning for
10 days(partitioned by date). data for each day around 130G. The problem is
not consistent since if you run it again, it might go through. but the
problem has never happened on the smaller jobs(like processing only one
days data).

We don't have space issue.

I have attached log file when problem happening. it is stuck like
following(just search "19706 of 49964")

2013-03-05 15:13:51,587 INFO org.apache.hadoop.mapred.TaskTracker:
