Brock Noland created HIVE-9128: ---------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
