Subject [jira] [Commented] (KAFKA-5526) ConsumerGroupCommand no longer shows output for consumer groups which have not committed offsets
Date Tue, 27 Jun 2017 18:25:00 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-5526?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16065253#comment-16065253
] 

Vahid Hashemian commented on KAFKA-5526:
----------------------------------------

[~hachikuji] Do you mean to have a special argument to display the group members and not any
offsets?
The other option is keeping the current output format and printing something like `N/A` during
the few seconds offsets are being initialized.

> It would appear that the latest iteration of the ConsumerGroupCommand no longer outputs
information about group membership when no offsets have been committed. It would be nice if
the output generated by these tools maintained some form of consistency across versions as
some users have grown to depend on them.
