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_
