---------------------------------------
Summary: Flaky Test `ReassignPartitionsIntegrationTest
.testCancellation`
Key: KAFKA-10061
URL: https://issues.apache.org/jira/browse/KAFKA-10061
Project: Kafka
Issue Type: Bug
Reporter: Jason Gustafson
Assignee: Jason Gustafson
We have seen this a few times:
```
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)
```
It looks like the reassignment is completing earlier than the test expects. See
the following from the log:
```
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.
```
A successful run looks like this:
```
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 still in progress.
```
