      Description

      Due to KAFKA-4204, we never realized that the existing system test for testing reassignment would always fail when brokers were bounced in mid process. This happens reliably, even for topics of varying number of partition and varying replication factors.

      In particular, we see errors like this in the logs when the brokers are bounced:

      Status of partition reassignment:
      ERROR: Assigned replicas (1,2) don't match the list of replicas for reassignment (1) for partition [test_topic,2]
      Reassignment of partition [test_topic,1] completed successfully
      Reassignment of partition [test_topic,2] failed
      Reassignment of partition [test_topic,3] completed successfully
      Reassignment of partition [test_topic,0] is still in progress
      

      Currently, the tests which bounce brokers during reassignment are disabled until this bug is fixed.
