Justine Olshan commented on KAFKA-15653:
----------------------------------------

I will definitely work on this [~divijvaidya].
I plan on moving the method appendEntries out and supplying the correct 
requestLocal in the callback.

I am also filing a new Jira to address the requestLocal's future, since this 
mistake was easy to make.
