Subject [jira] [Commented] (KAFKA-6158) CONSUMER-ID and HOST values are concatenated if the CONSUMER-ID is > 50 chars
Date Thu, 02 Nov 2017 15:08:01 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-6158?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16235878#comment-16235878
] 

Vahid Hashemian commented on KAFKA-6158:
----------------------------------------

Those columns are fixed length. So if the value length is at or above the column length this
would happen. I'll try to make it look better as part of the work I'm doing for [KAFKA-4682|https://issues.apache.org/jira/browse/KAFKA-5526].
