Hi,
I am experiencing one situation that the log cleaner dose not work for the related topic-partition when using kafka-reassign-partitions.sh tool for V2.1.1 for more than one time frequently. My operation: submitting one task for migration replica in one same broker first, when the previous task still in progress, we submit one new task for the same topic-partition. My search: server executes abortAndPauseCleaning() once task is submitted, shortly, another task is submitted for the same topic-partition, so the clean thread status is LogCleaningPaused(2) currently. When the second task completed, the clean thread will be resumed for this topic-partition once. In my case, the previous task is killed directly, no resumeClean() is executed for the first task, so when the second task is completed, the clean status for the topic-partition is still LogCleaningPaused(1), which blocks the clean thread for the topic-partition. That's all my search, please confirm. Thanks Nora
