LocalBookKeeper is initializing the zkclient and immediately trying to create "/ledgers" and "/ledgers/available" znodes without waiting for the ZooKeeper SyncConnected state. The client operation should be guarded with ZKConnectionWatcher.

Assuming the vote on the current release candidate passes, one option is to have a bug fix release 4.1.1 that includes this issue rather than wait until 4.2.0.

Rakesh R updated BOOKKEEPER-279:
--------------------------------
Attachment: BOOKKEEPER-279.1.patch
Thanks Sijie. Updated the patch by fixing the comment. Since ZooKeeperDefaultPort is always 2181, I have reused the HOSTPORT='127.0.0.1:2181' as connectstring.

Attachment: BOOKKEEPER-279.patch
Attached the patch. Didnot include any test case as the zk instance is not visible. Appreciate any ideas:)
Also, I have corrected the sessiontimeout parameter in the patch.

-------------------------------------
Since you already cut the branch and not a blocker issue, agree moving to 4.2.0 version. If you have chance to do one more RC, then will include this also. I'll manage internally this.

Sijie Guo commented on BOOKKEEPER-279:
--------------------------------------
the patch seems good to me. just one comment.
{code}
- zkc = new ZooKeeper("127.0.0.1", ZooKeeperDefaultPort, new emptyWatcher());
+ CountdownWatcher zkConnectionWatcher = new CountdownWatcher();
+ zkc = new ZooKeeper("127.0.0.1", zkSessionTimeOut,
+ zkConnectionWatcher);
{code}
from my knowledge, if user doesn't specify zookeeper port in connect string, it would use default port to connect. so if I changed ZooKeeperDefaultPort, the ZooKeeper instance would not work probably. So why not append ZooKeeperDefaultPort after '127.0.0.1'?

oh, I just noticed that the jira is marked as 4.1.0. But I have cut a release 4.1.0 before this jira.
[~rakeshr] I would suggest moving it into 4.2.0. Is it OK for me?
