> We have seen this a few times:
> {code}
> org.scalatest.exceptions.TestFailedException: Timed out waiting for
> verifyAssignment result VerifyAssignmentResult(Map(foo-0 ->
> PartitionReassignmentState(List(0, 1, 3, 2),List(0, 1, 3),false), baz-1 ->
> PartitionReassignmentState(List(0, 2, 3, 1),List(0, 2,
> 3),false)),true,Map(),false). The latest result was
> VerifyAssignmentResult(Map(foo-0 -> PartitionReassignmentState(ArrayBuffer(0,
> 1, 3),List(0, 1, 3),true), baz-1 -> PartitionReassignmentState(ArrayBuffer(0,
> 2, 3),List(0, 2, 3),true)),false,HashMap(),false)
> {code}
> It looks like the reassignment is completing earlier than the test expects.
> See the following from the log:
> {code}
> Successfully started partition reassignments for baz-1,foo-0
> ==> verifyAssignment(adminClient,
> jsonString={"version":1,"partitions":[{"topic":"foo","partition":0,"replicas":[0,1,3],"log_dirs":["any","any","any"]},{"topic":"baz","partition":1,"replicas":[0,2,3],"log_dirs":["any","any","any"]}]})
> Status of partition reassignment:
> Reassignment of partition baz-1 is still in progress.
> Reassignment of partition foo-0 is complete.
> {code}
> A successful run looks like this:
> {code}
> Successfully started partition reassignments for baz-1,foo-0
> ==> verifyAssignment(adminClient,
> jsonString={"version":1,"partitions":[{"topic":"foo","partition":0,"replicas":[0,1,3],"log_dirs":["any","any","any"]},{"topic":"baz","partition":1,"replicas":[0,2,3],"log_dirs":["any","any","any"]}]})
> Status of partition reassignment:
