SessionExpiredException. help!
Yuhan Zhang 2011-09-23, 21:50
Hi all,

I set the sessionTimeout value to be "Integer.MAX_VALUE" to the constructor
as
 zooKeeper = new ZooKeeper(host, Integer.MAX_VALUE, this);
but reached an "session expired" exception when requesting a create
operation twice on the following line:

lockPath = zooKeeper.create( lockFolder + "/0", new byte[0],
Ids.OPEN_ACL_UNSAFE, CreateMode.EPHEMERAL_
SEQUENTIAL);

Exception:
org.apache.zookeeper.KeeperException$SessionExpiredException :
KeeperErrorCode = Session expired for /_lock/0
why does this happen? could anyone give some advice?
Thank you.

Yuhan
