Unusual exception
I started seeing a bunch of these exceptions. What do these mean?

Re: Unusual exception

EOS means that the client closed the connection (from the point of view of
the server). The server then tries to cleanup by closing the socket
explicitly, in some cases that results in debug messages you see subsequent.
EndOfStreamException: Unable to
read additional data from client sessionid 0x0, likely client has closed
socket
Notice that the session id is 0 - so either this is a zk client that failed
before establishing a session, or more likely it's a monitoring/4letterword
command (which never est sessions).

Hi Vineet,
You probably meant to send this message to the Kafka list, no?

Hi Avinash,
I am facing the same problem.
I am unable to detect the source of the problem as the producer program is
working but consumer is not.
Can you please help me out.

I'm new to Zookeeper. The first tests all worked but now I'm getting the same
exception as the previous posters. Unfortunately I don't see the answer.
My situation is that I have the zookeeper server running on my PC and am in
a cluster with two other servers. I'm on Windows and just run the ZkCli.cmd
script multiple times on my PC. The first two start fine, but the third
gives this error message:
zookeeper.ClientCnxn: Opening socket connection to server
localhost/127.0.0.1:2181
zookeeper.ClientCnxn: Socket connection established to
localhost/127.0.0.1:2181, initiating session
zookeeper.ClientCnxn: Unable to read additional data from server sessionid
0x0, likely server has closed socket, closing socket connection and
attempting reconnect
Is there a limit somewhere on number of client connections? Or is it a
problem on my Windows PC with sockets?
Any help would be appreciated.
Adje

Re: Unusual exception

This is saying that the client (hbase in this case) is no longer
connected to the server (tcp connection down) for some reason. This
can happen for a number of reasons - typically the client process was
killed, host restarted or partitioned from the server, etc.... There's
nothing really to "solve" here, once the issue is resolved, ie client
process is restarted or network healed etc..., the client will
re-connect and start participating again.

Hi,

Re: Unusual exception
Posted by Mahadev Konar <ma...@yahoo-inc.com>.
Hi Avinash,
Not sure if you got a response for your email.
The exception that you mention mostly means that the client already closed
the socket or shutdown.
Looks like a client is trying to connect but disconnects before the server
can respond.
Do you have any such clients? Is this causing any issues with your zookeeper
set up?
Thanks
mahadev
