Hi,
Is there a way to bound the number of outstanding requests when using the
async api? Currently, it seems that a client can run out of memory if it
sends async requests too quickly.
Thanks,

Hi,
Does ZK guarantee that ephemeral nodes from a client are removed on the
sever by the time the client receives a session expiration event? I am
getting conflicting info on this (
https://issues.apache.org/jira/browse/KAFKA-4277). Could someone clarify?
Thanks,
Jun
Hi,
When a child watcher is fired, it can happen that when the children are
read, a deleted node is already added back. So, from the list of children,
it's as if nothing has changed. However, it could be important for an app
to know in this case that something has changed. I could include some
+
seconds (that's not a mistake - seconds) for fsync to complete. When
this happened (every few hours) all of the sessions would timeout.
See this article:

Hi,
It seems that the create API doesn't return Stat. So, the client can't
figure out the initial version id of a path after it's created. Should the
client just assume that the initial version is always 0?
Also, what's the difference between getVersion and getCVersion?
Thanks,
Jun
Jamie,
We do use chroot. However, the chroot problem will lose all watchers, not
some watchers, right?
Thanks,

Hi Neha,
I encountered a similar problem with zookeeper losing watches and found
that it was

should have one/more, including the most important fixes until 3.4.x
code line has stabilized for production use.

Has the release date for ZK 3.4 be determined? Thanks,

Hi
to
handle this. Thomas provided a patch with tests that presumably show the
error, so all you need is a fix to make them pass.

I have a ZK server cluster running on 4 nodes (version 3.3.3) and a few ZK
clients (version 3.3.0). After the clients have been running for a while,
each of them starts to constantly disconnect and reconnect to the ZK server.
On the client, I saw lots of entries like the following:
2011/08/23
about why you are using 4 ZK servers. This doesn't increase availability
or
durability over having just three ZK servers.

I like to have ZK itself manage the amount of snapshots and logs kept,

Hmm, those logs are pretty big, there is a 67MB file per hour.

I don't expect that we can discover the problem right now. However, what
are
the things
can think of are:
1) the change happened before the watch was set
2) the change never got there
you could get an answer to both of those questions by looking at the
transaction log.

No it cannot happen without a zookeeper restart.
Are you sure you are shutting down the client?
