@afilpp @sarvekshayr @sumitagrawl @Tejaskriya can you please help review this?

[Montura]

Thanks for the patch @Montura. Are you also planning to move the other tests in TestContainerBalancerTask to TestContainerBalancerDatanodeNodeLimit with new PRs?

Sure, I have plans to finish it in one or two PRs (@siddhantsangwan has told first time that too many lines per one PR).

I'd like to finish in one PR of course.

Splitting it into many PRs will make it easy for reviews, it makes sense. Thanks for addressing the comments, LGTM
