Review request for hive and Xuefu Zhang.
Bugs: HIVE-7873
https://issues.apache.org/jira/browse/HIVE-7873
Repository: hive-git
Description
-------
Re-enabled lazy HiveBaseFunctionResultList. A separate RowContainer is used to
work around the no-write-after-read limitation of RowContainer. The patch also
fixed a concurrency issue in HiveKVResultCache. Synchronized is used instead of
reentrant lock since I assume there won't be many threads to access the cache.
