-----------------------------------

             Summary: Log Cleaner Stopped
                 Key: KAFKA-9762
                 URL: https://issues.apache.org/jira/browse/KAFKA-9762
             Project: Kafka
          Issue Type: Bug
          Components: log, log cleaner

There is only one topic not able to get cleaned, other topics works fine.

Topic Config are shown as below,

PartitionCount:2 

ReplicationFactor:3 

Configs:retention.ms=3601000

segment.ms=1801000

Broker config:

log.cleaner.thread=1

The oldest data is on Feb27th. We have seen the log cleaner was stopped or got in stuck for that topic.(We haven't see "Scheduling log segment....." afterwards....)

Also We have ran some query for metrics

kafka.log:logDirectory="/opt/kafka/data/logs",name=uncleanable-partitions-count,type=LogCleanerManager

Result:0
kafka.log:name=OfflineLogDirectoryCount,type=LogManager
Result:0
kafka.log:name=max-dirty-percent,type=LogCleanerManager

Result:48
kafka.log:name=time-since-last-run-ms,type=LogCleanerManager

Result: few seconds ago
