Hi guys,
Thank you for your response.
I read the zk's source code of Friday and found out that in case of failed
authentication the KeeperState is changed to KeeperState.AuthFailed but in case
of successful one nothing happens - neither any triggers are called nor status
is changed. KeeperState remains the same as before the call of authentication.
So, it is not obvious if the authentication is completed and not or if it was
called or not at all.
In the ClientCnxn.SendThread class, method readResponse(), line 766:
....
if (replyHdr.getXid() == -4) {
// -4 is the xid for AuthPacket
if(replyHdr.getErr() ==
KeeperException.Code.AUTHFAILED.intValue()) {
zooKeeper.state = States.AUTH_FAILED;
eventThread.queueEvent( new
WatchedEvent(Watcher.Event.EventType.None,
Watcher.Event.KeeperState.AuthFailed, null) );
}
if (LOG.isDebugEnabled()) {
LOG.debug("Got auth sessionid:0x"
+ Long.toHexString(sessionId));
}
return;
}
....
If it is successful - nothing is called.
Is it supposed how it should behave? If it is then I have to catch the
exception, process it (if it is actually authentication exception) and re-try
my call (e.g. create znode) until it is successful. Not easy and obvious, isn't
it?
Regards,
Semyon

In general i'm pretty happy with our docs, however Auth docs are an area where
we could use some help.... ;-) Would be great if someone wanted to work on this.
