hiveserver2".

INLINE COMMENTS
  ql/src/java/org/apache/hadoop/hive/ql/exec/DefaultFetchConverter.java:50 ok
  common/src/java/org/apache/hadoop/hive/conf/HiveConf.java:667 Yes, it seemed not useful
by exposing to end user. Will be moved to SQLOperation.
  ql/src/java/org/apache/hadoop/hive/ql/exec/ListSinkOperator.java:57 ok.
  service/src/java/org/apache/hive/service/cli/operation/SQLOperation.java:98 It should be
an internal configuration not exposed to user, as commented in HiveConf. I'll add comments
for that.

> Current hiveserver2 acquires rows in string format which is used for cli output. Then
convert them into row again and convert to final format lastly. This is inefficient and memory
consuming.
