[jira] [Created] (KAFKA-8463) Fix redundant reassignment of tasks when leader worker leaves

Konstantine Karantasis created KAFKA-8463:
---------------------------------------------

             Summary: Fix redundant reassignment of tasks when leader worker leaves
                 Key: KAFKA-8463
                 URL: https://issues.apache.org/jira/browse/KAFKA-8463
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 2.3.0
            Reporter: Konstantine Karantasis
            Assignee: Konstantine Karantasis
             Fix For: 2.3.0


There's a bug in the computation of new assignment for connectors and tasks in \{{IncrementalCooperativeAssignor}} that may lead to duplicate assignment. The existing assignments should always be considered because if the leader worker bounces there's no history of previous assignments.
