Alexander Pivovarov commented on HIVE-10748:
--------------------------------------------
Build 4130 has 3 failed tests. I think errors are unrelated to the patch #2.
I checked prev build 4129 - it also has the same 3 failed tests.
So, everything looks good!

> I found 40 places in Hive where "new StringBuffer(" is used.
> "Where possible, it is recommended that StringBuilder be used in preference
