Subject [jira] [Commented] (KAFKA-4577) NPE in ControllerChannelManager.scala::addUpdateMetadataRequestForBrokers
Date Wed, 11 Jan 2017 17:34:48 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-4577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15818922#comment-15818922
] 

Scott Reynolds commented on KAFKA-4577:
---------------------------------------

Nothing interesting was happening, obviously ISR change was happening but it wasn't triggered
by a human.

Had this happen again yesterday. 

It is unclear to me what is set to null and how it got to that state for this:
{code:java}
controller.deleteTopicManager.partitionsToBeDeleted.isEmpty
{code}
