Sushanth Sowmyan commented on HIVE-2800:
----------------------------------------
Ashutosh, digging a bit more into thrift sources, this is what I find:
http://svn.apache.org/repos/asf/thrift/trunk/lib/java/src/org/apache/thrift/protocol/TBinaryProtocol.java
If you look at the method writeString there, it does not check for null, it
calls str.getBytes(). So as of thrift trunk, this does not work. I'm not sure
if that's intentional on thrift's part (to maximize speed by minimizing checks)
and something to fix on hive's side, or something to fix on thrift's side.
In the meanwhile, I've added a testcase for this bug in the
RemoteHiveMetaStore, I'm updating the patch now.
