I have a simple query with grouping. Something similar to bellow:
SELECT col1, col2, col3, min(date), count(*)
FROM tblX
WHERE partitionDate="20141107"
GROUP BY col1, col2, col3;
When I run this query through WebHCat everything works fine. But when I try
to run it from hive shell I have error like this:
Setting job diagnostics to REDUCE capability required is more than the
supported max container capability in the cluster. Killing the Job.
reduceResourceReqt: 21238 maxContainerCapability:8192
I tried to setup in hive: SET hive.exec.reducers.max=8192
but this doesn't change anything. What I did wrong?
