Hello, In my Hive cluster, I have setup the mapred.reduce.tasks to be -1 i.e. I am allowing HIVE to figure out the # of reducers that it would need from the data.
When I run a query, it determines that it will need 4 reducers but when I look at the MAPRED logs, I see that all the work is done by a single reducer while the other 3 reducers forward 0 rows. Is this just bad planning on HIVE side or am I missing something. Thanks, Viral
