abbccdda commented on pull request #6666: KAFKA-8220: Avoid kicking out members
through rebalance timeout
URL: https://github.com/apache/kafka/pull/6666
To make consumer group members more persist, we want to avoid kick-out
unjoined members through rebalance timeout. The only exception is when leader
fails to join, because we will at risk of no assignment computed during sync
stage. The choice will be kicking off non-responsive leader and choose a new
leader if possible.
