Prasanth Jayachandran commented on HIVE-15115:
----------------------------------------------

I guess the tests are not failing because it is getting instances from the same 
region (PST). If it gets instances from different regions then this can fail. 
May be we should build a better resiliency for these file size related 
differences in qtestutil. Another option would be add a new marker "TIMEZONE 
SENSITIVE TEST" to the q file and mask total file size during result comparison 
that have the marker?
