GitHub user ijuma opened a pull request:
https://github.com/apache/kafka/pull/1985
MINOR: A bunch of clean-ups related to usage of unused variables
There should be only 2 cases where these clean-ups have a functional impact:
1. Fix a bug in the newly introduced `fetchAllChildEntityConfigs` where we
are concatenating
`Some(s)` instead of `s`.
2. Replaced repeated identical logs with a single log for the stale
controller epoch case
The rest should just make the code easier to read and make it a bit less
wasteful. I did this exercise because unused variables sometimes mask bugs.

Avoid unnecessary `toSet` and replace pattern matching by `isDefined`

Replace one log entry per partition with a single log entry for a stale
controller epoch error
Since the same information was printed each time, it seems completely
pointless to print it
multiple times.
