-----------------------------------
navis has commented on the revision "HIVE-5276 [jira] Skip useless string
encoding stage for 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.

> This is inefficient and memory consuming.
