Subject [jira] [Commented] (HIVE-5263) Query Plan cloning time could be improved by using Kryo
Date Thu, 12 Sep 2013 05:17:53 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5263?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13765164#comment-13765164

Brock Noland commented on HIVE-5263:
------------------------------------

That'd be great. Also TestSequenceFileReadWrite passes locally with the patch. Indeed org.apache.hcatalog.mapreduce.TestSequenceFileReadWrite,
this test's clone passed in the ptest run above.

> In HIVE-1511 we implemented Kryo for serialization but did not use for query plan cloning.
As was discussed there it's a possible speed improvement. In addition the current XML serialization
method does not work with Java 7 so using Kryo is a workaround for this issue.
