sijie opened a new issue #1126: ZK Ledger Manager doesn't handle zookeeper session expires URL: https://github.com/apache/bookkeeper/issues/1126 **BUG REPORT** *Problem* @jvrao mentioned this at slack channel ``` Just trying to understand the current code in the following scenario: Two clients Client-1 writing a ledger Client-2 tailing the same ledger (with lac updates etc) client-2 lost connection with ZK client-1 lost connection with bookies and replaced entire ensemble. Now client-2 can't get ensemble change update as its lots its session also client-2 can't read new LAC as all bookies that it is talking to have old LAC and apparently we don't handle session expiry on readonly ledger handle watcher so what happens? the reader hangs for-ever? ``` The expected behavior : ledger manager will handle session expires and register watcher on the ledger metadata. However in current apache/master there is no session expire handling logic in ledger manager. This logic exists only at twitter/master. This issue is to port that change back from twitter/master to apache/master.
