UI is unable to display consumer groups for a topic

Symptoms

The Event Streams UI is unable to display consumer groups for a particular topic and the log output for the Admin REST component shows an exception similar to the following:

java.lang.IllegalArgumentException: Invalid negative offset

Causes

See Kafka issue 9507.

When processing a list offsets request, the Kafka AdminClient does not filter out offsets with value -1, and receives an IllegalArgumentException when it creates the response.

Resolving the problem

Contact IBM Support to request a fix, and include issue number 139 in your correspondence.

Resolved in Event Streams version 10.0.0 and later.
