    Description

      Reported by Gary Russell in the 2.6.1 RC3 vote thread

      I am seeing this on every consumer start:

      2020-11-25 13:54:34.858 INFO 42250 — ntainer#0-0-C-1 o.a.k.c.c.internals.AbstractCoordinator : [Consumer clientId=consumer-ktest26int-1, groupId=ktest26int] Rebalance failed.

      org.apache.kafka.common.errors.MemberIdRequiredException: The group member needs to have a valid member id before actually entering a consumer group.

      Due to this change https://github.com/apache/kafka/commit/16ec1793d53700623c9cb43e711f585aafd44dd4#diff-15efe9b844f78b686393b6c2e2ad61306c3473225742caed05c7edab9a138832R468

      I understand what a MemberIdRequiredException is, but the previous (2.6.0) log (with exception.getMessage()) didn't stand out like the new one does because it was all on one line.
