----------------------------------
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.
