[jira] [Commented] (KAFKA-7170) NPE in ConsumerGroupCommand when
describe consumer group
[ https://issues.apache.org/jira/browse/KAFKA-7170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16545748#comment-16545748 ]
Ted Yu commented on KAFKA-7170:
-------------------------------
Can you provide a bit more information: release of Kafka, etc.
If you can describe sequence of events leading to the NPE, that would be easier to investigate.
