Arvind Prabhakar updated HIVE-1176:
-----------------------------------
Status: Patch Available (was: Open)
Assignee: Arvind Prabhakar
This problem is due to [a bug in Datanucleus
JDOQL|http://www.jpox.org/servlet/jira/browse/NUCCORE-427] implementation and
has been fixed in version 2.0.x.
The fix is therefore to upgrade datanucleus plugins to the latest stable
release.
*Details:*
- Replaced the old datanucleus plugins version 1.1.2 with the latest stable
release.
- Updated jdo2-api library with the version required by datanucleus - 2.3-0ec,
available from datanucleus maven repository at
http://www.datanucleus.org/downloads/maven2/javax/jdo/jdo2-api/2.3-ec/, Apache
licensed
- Modified the build files to suppress auto-enhancement of all complied
classes, a new feature introduced in the latest version.
- Modified the HiveMetaStoreClient implementation to create deep-copies of
non-primitive objects being returned from the thrift server. Without this
change, some collections were being fetched as semi-populated proxies with
missing session context leading to NPEs.
*Testing Done:*
Built and ran all tests. Only two failures were reported - clientpositive test
for input20.q and input33.q. These tests appear to be failing on the trunk as
well.
