Leo Romanoff commented on HIVE-1511: ------------------------------------ @[~brocknoland] The problem with deserialization that you reported am 21 August seems interesting. It could be an indication of a bug in Kryo. At the first glance it looks as if there is a bug in serialization of strings or in writing/reading object references. I'll look into it if time permits. It would be very nice to get a reduced version of this test (e.g. only the data structure that fails and the content of fields that leads to it), which can be easily reproduced as a JUnit-test for Kryo. -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: 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 > > > 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.
