Leo Romanoff commented on HIVE-1511: ------------------------------------ [~kamrul] I think I fixed the problem you reported. Your test seems to pass now on my side. I fixed the bug in Kryo (and it was a serious one related to usage of nested generic classes, e.g. Maps of Maps) and it is just committed into Kryo trunk. Simply update your Kryo 2.22-SNAPSHOT to make sure it uses the latest trunk and you should be fine. -Leo > Hive plan serialization is slow > ------------------------------- > > Key: HIVE-1511 > URL: https://issues.apache.org/jira/browse/HIVE-1511 > Project: Hive > Issue Type: Improvement > Affects Versions: 0.7.0 > Reporter: Ning Zhang > Assignee: Mohammad Kamrul Islam > Attachments: generated_plan.xml, HIVE-1511.4.patch, > HIVE-1511.5.patch, HIVE-1511.6.patch, HIVE-1511.7.patch, HIVE-1511.8.patch, > HIVE-1511.patch, HIVE-1511-wip2.patch, HIVE-1511-wip3.patch, > HIVE-1511-wip4.patch, HIVE-1511-wip.patch, KryoHiveTest.java, run.sh > > > As reported by Edward Capriolo: > For reference I did this as a test case.... > SELECT * FROM src where > key=0 OR key=0 OR key=0 OR key=0 OR key=0 OR key=0 OR key=0 OR key=0 > OR key=0 OR key=0 OR key=0 OR > key=0 OR key=0 OR key=0 OR key=0 OR key=0 OR key=0 OR key=0 OR key=0 > OR key=0 OR key=0 OR key=0 OR > ...(100 more of these) > No OOM but I gave up after the test case did not go anywhere for about > 2 minutes. -- This message is automatically generated by JIRA.
