It's only use 50% Computational resource of my cluster when using Hive on Tez

it can use 100% Computational resource of my cluster when using Hive on MR, but only use 50% computational resource when using Hive on Tez. I use Ambari to deploy my HDFS, YARN, Hive, Tez, Zookeeper, and use the recommended configure.

I want to know how to make hive on tez to use 100% computational resource

@Dylan Wu

May be your MapReduce is using a different queue than Tez. how are your queues configured?

@mquresh

Thank you very much. You are right, I only set mapreduce.job.queuename, but not set the tez.queue.name, so It only use the default queue which only using 30% computational resource using Hive on Tez.
