Zookeeper connection error

Question

We have a standalone zookeeper setup on a dev machine. It works fine for every other dev machine except this one testdev machine.

We get this error over and over aga

Answer 1

In my case, I config zoo.cfg like this:

server.1=host-1:2888:3888
server.2=host-2:2888:3888
server.3=host-3:2888:3888

But, in host-1, I config host-1 resolve to 127.0.0.1 in /etc/hosts:

127.0.0.1   localhost host-1

which may results other hosts can't communicate with it. Resolve host-1 to its real ip solved this problem.

Hope this can help.
