             Summary: Cleaning thread blocked  when more than one ALTER_REPLICA_LOG_DIRS requests sent
                 Key: KAFKA-8738
                 URL: https://issues.apache.org/jira/browse/KAFKA-8738
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 2.1.1
            Reporter: dingsainan


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:
Kafka executes abortAndPauseCleaning() once task is submitted, shortly, another task is submitted for the same topic-partition, so the clean thread status is {color:#ff0000}LogCleaningPaused(2){color} 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 {color:#ff0000}LogCleaningPaused(1){color}, which blocks the clean thread for the topic-partition.
 
_That's all my search, please confirm._
 
_Thanks_
_Nora_
