问题
I am running a hive query and I got the following error when setting the hive.execution.engine=tez, while the query is working under engine=MR.
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.tez.TezTask
My query is an inner join and the data is quite big.
Another thing is that I have met this problem before. But tez works later so I thought it was about something unstable about hive.

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.
