[jira] [Created] (KAFKA-13305) NullPointerException in LogCleanerManager "uncleanable-bytes" gauge

Vincent Jiang created KAFKA-13305:
-------------------------------------

             Summary: NullPointerException in LogCleanerManager "uncleanable-bytes" gauge
                 Key: KAFKA-13305
                 URL: https://issues.apache.org/jira/browse/KAFKA-13305
             Project: Kafka
          Issue Type: Bug
          Components: log cleaner
            Reporter: Vincent Jiang


We've seen following exception in production environment:
{quote} java.lang.NullPointerException: Cannot invoke "kafka.log.UnifiedLog.logStartOffset()" because "log" is null at

kafka.log.LogCleanerManager$.cleanableOffsets(LogCleanerManager.scala:599)
{quote}
Looks like uncleanablePartitions never has partitions removed from it to reflect partition deletion/reassignment.

 

We should fix the NullPointerException and removed deleted partitions from uncleanablePartitions.
