Subject problem starting ensemble mode
Date Thu, 01 Oct 2009 22:59:23 GMT
Hi all,

I am trying to start zookeeper in two nodes, the configuration file I have
is

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/zookeeper
clientPort=2181
server.1=hec-bp1:2888:3888
server.2=hec-bp2:2888:3888


i also have two files /var/zookeeper/myid  on each of the machines, the
files contain 1 and 2 on each of the servers


When I start, I get the following

Starting zookeeper ...

I can expect these kind of messages when the other server hasn't been
started, but even after a while keeps sending these messages.

I can ping and ssh between the machines.
I noticed that just port 3888 is listening when I do netstat -an, why is
port 2888 not being used?

Any ideas?

Thanks
