It is not needed to add [Metric Hadoop] string in the changelog

[harnish-elastic]

Updated, thanks!

I assume, the panel at the top is the time duration it takes .
In the panel below, does the "Duration" text in the "Container Launch Duration (Num of operation) " make sense? Please change from Num of operation to Operation Count.

This name is already there in the current codebase. This is just the lens migration PR so we won't be changing any behavior as a part of this PR otherwise it will mess it up. However, If you strongly feel that this change needs to be done then we can raise a separate issue for that and track them separately.

As you think that the change will complicate the PR, continue with the same scope.
