Answer 1

While running your HQL via hive include following parameter. This will give you detailed logs and you can determine the root cause easily.

-hiveconf hive.root.logger=DEBUG,console

I faced similar problem and above property help me big time.

e.g.: I got following message

16/04/14 10:29:26 ERROR exec.Task: Failed to execute tez graph.
org.apache.tez.dag.api.TezException: org.apache.hadoop.yarn.exceptions.InvalidResourceRequestException: Invalid resource request, requested memory < 0, or requested memory > max configured, requestedMemory=20480, maxMemory=11288

When I changed my setting to 11288, my query went through fine.

Hope this will help you.
