> In https://issues.apache.org/jira/browse/KAFKA-4521 we fixed a potential message reorder bug in MM. However, the patch introduced another bug that can cause deadlock during MM shutdown. The deadlock will happen if zookeeper listener thread call requestAndWaitForCommit() after MirrorMaker thread has already exited loop of consuming and producing messages.
