László Bodor commented on HIVE-24138:
-------------------------------------
[~ayushtkn]: I can see in the pull request that you almost achieved a green run
without upgrading hadoop/guava, which is promising, but I'm a bit confused
about the contradictional contents of the consecutive commits...is it possible
to squash and force push them to easily see an overall picture on the PR? this
will result in a smaller commit, and maybe helps us to decide how to solve this
issue finally?
