Review request for hive.


Changes
-------

address ashutosh's comments, remove unnecessary txns


Repository: hive-git


Description
-------

The previous solution https://issues.apache.org/jira/browse/HIVE-7736
is not enough for the case when there are too many columns/partitions.
The user will encounter
org.apache.thrift.transport.TTransportException: java.net.SocketTimeoutException: Read timed
out
We try to remove more of transaction overhead
