Review request for hive, Szehon Ho, Thejas Nair, and Xuefu Zhang.
Changes
-------
Updated the patch based on Vaibhav's review. Thanks
Bugs: HIVE-10835
https://issues.apache.org/jira/browse/HIVE-10835
Repository: hive-git
Description
-------
There exist race conditions between DatabaseMetaData, Statement and ResultSet
when they make RPC calls to HS2 using same Thrift transport, which happens
within same connection.
The patch is to have a connection level lock to serialize the RPC calls within
a single connection.
