ZooKeeper ClientCnxn : Attempting connection to server(0.20 alpha)
Hi there,
I want to start a few HTable clients to read data in parallel from HBase.
While I starting 2 clients, it works fine.
But while I increase to 10 clients at the same time, some clients will
raise some message like Attempting connection to server.
Does anybody know what's going on?
Does ZooKeeper have connection limit setting?
Thanks
Fleming

Please update to TRUNK. We've fixed a bunch of issues since alpha including
one where we were not caching -ROOT- region and all clients went to
zookeeper everytime to find it putting a high load on zk.
Yes there is a connection limit setting. I think its in zoo.cfg. Else,
see zk site for doc. on zoo.cfg options.
