Zian Chen commented on YARN-8504:
---------------------------------
Agree with [~elgoiri] , we need to add some UTs to make sure this doesn't break
in the future when new columns added. Changing this by manually counting and
fixing the digits everytime is not a very good idea.
[~jutia] , could you add some UTs to this to address test4tests warmings?
Thanks!
