Ismael Juma commented on KAFKA-3123:
------------------------------------

Moving to 0.11.0.1 as there is no PR ready for review. If we get one during the RC period, we may bring this back into 0.11.0.0.

> I was trying to upgrade our test Windows cluster from 0.8.1.1 to 0.9.0 one machine at a time. Our logs have just 2 hours of retention. I had re-imaged the test machine under consideration, and got the following error in loop after starting afresh with 0.9.0 broker:

> I could unblock myself with a code change. I deleted the action for "case s =>" in the LogCleanerManager.scala's abortAndPauseCleaning(). I think we should not throw exception if the state is already LogCleaningAborted or LogCleaningPaused in this function, but instead just let it roll.
