> 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.
