Subject [jira] [Commented] (HIVE-9128) Evaluate hive.rpc.query.plan performance [Spark Branch]
Date Wed, 17 Dec 2014 00:23:13 GMT


Brock Noland commented on HIVE-9128:

Agreed that a second isn't very helpful for our use case. Perhaps we'll hold off on this one
for now.

> Tez uses [hive.rpc.query.plan|]
which is used in {{}}. 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.
