[jira] [Created] (HIVE-9128) Evaluate hive.rpc.query.plan performance [Spark Branch]

----------------------------------

             Summary: Evaluate hive.rpc.query.plan performance [Spark Branch]
                 Key: HIVE-9128
                 URL: https://issues.apache.org/jira/browse/HIVE-9128
             Project: Hive
          Issue Type: Sub-task
            Reporter: Brock Noland


Tez uses [hive.rpc.query.plan|https://github.com/apache/hive/blob/trunk/common/src/java/org/apache/hadoop/hive/conf/HiveConf.java#L1874] which is used in {{Utilities.java}}. Basically instead of writing the query plan to HDFS, the query plan is placed in the JobConf object and then de-serialized form there.

We should do some evaluation to see which is more performant for us. We might need to place some timings in {{Utilities}} to understand this if the PerfLog doesn't have enough information today.
