Gaurav Narula commented on KAFKA-16045:
---------------------------------------
I've observed that {{allTopics}} seems to contain {{"topic-1", "topic-2",
"topic-3"}} and {{topicDeletions}} is empty in
[ZkTopicMigrationClient::iterateTopics|https://github.com/apache/kafka/blob/127fe7d2765cfdcee6243cbc62a77a7760b3c84c/core/src/main/scala/kafka/zk/migration/ZkTopicMigrationClient.scala#L52]

> I'm seeing ZkMigrationIntegrationTest.testMigrateTopicDeletion fail for many

> it fails I also see ReplicaManager tests also fail with extra threads.
> The test always fails
