Sunil Govindan commented on YARN-8492:
--------------------------------------

A few of ATS v2 patches are blocked due to this ClassNotFound exception while 
running test cases with Hbase profile 1.2.6. I agree to [~rohithsharma]' 
suggestion of fixing this patch so that other jiras can move forward. But there 
should be another Blocker/Critical Jira to track this. cud u pls help to create 
one?
