Subject Re: Seeking Help configuring log4j for sqoop import into hive
Date Tue, 12 Nov 2013 13:29:53 GMT
Thanks Jarcec. You are right the map task log is what I am looking for but
I don't see it. The warning just below the 'caused by' line indicates its
not set up right.

I'll redirect the query to sqoop user group. Please let me know if you have
any pointers to get the map task log.
