Subject Hive Reduce error
Date Sat, 03 Sep 2011 01:08:29 GMT
Hi,
I'm pretty sure I've seen this error before on a regular hadoop job but I don't know how to
fix this. Can anyone hint to what might be causing this? I'm runnign Brisk hive, but I think
this is a more generic Hadoop error caused by some setting I have wrong.
