[jira] [Commented] (KAFKA-19112) cleanup.policy shouldn't be empty

    [ https://issues.apache.org/jira/browse/KAFKA-19112?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17942029#comment-17942029 ] 

Jun Rao commented on KAFKA-19112:
---------------------------------

We can tighten up the validation for those configs. However, not sure about incorrect values already in place. One option is to just fail fast in that case. We probably need a KIP if we do that.

> Currently, we allow a user to set cleanup.policy to be an empty list, which shouldn't be allowed. A few other configs of List type such as
> group.coordinator.rebalance.protocols and process.roles have the same problem.
