Sriharsha Chintalapani commented on KAFKA-1558:
-----------------------------------------------
[~nehanarkhede] I was trying to test if the controller is recovering from a
soft failure successfully and above described behavior is outcome of issuing a
delete topic command not necessarily anything to do with controller's ability
to come out of soft failure.
Hence I removed the producers/consumers and didn't do delete topic command even
than the old controller didn't shutdown properly and I believe this is what
causing the delete topic to fail. Since the old controller didn't shutdown
topic partition goes to offline which is causing new controller's
TopicDeletionManager go into a loop where one of the topic partition replica's
are offline and keep retrying to delete it.
> AdminUtils.deleteTopic does not work

> the AdminUtils:.deleteTopic method is implemented as
> {code}
> def deleteTopic(zkClient: ZkClient, topic: String) {
> ZkUtils.createPersistentPath(zkClient,
> ZkUtils.getDeleteTopicPath(topic))
> }
> {code}
> but the DeleteTopicCommand actually does
> {code}
> zkClient = new ZkClient(zkConnect, 30000, 30000, ZKStringSerializer)
> zkClient.deleteRecursive(ZkUtils.getTopicPath(topic))
> {code}
> so I guess, that the 'createPersistentPath' above should actually be
> {code}
> def deleteTopic(zkClient: ZkClient, topic: String) {
> ZkUtils.deletePathRecursive(zkClient, ZkUtils.getTopicPath(topic))
> }
> {code}
