Hi Biao,

Thanks for your reply, fortunately the problem is solved.
All I did was changed the bind-host to 0.0.0.0 (previously it was set to
the server's IP).

I don't know if it's best practice or not but everything is working fine
now.

RIght now I am using flink as standalone (I have the binaries in Centos and
just run it using the ./start-cluster command), but I want to learn on how
to set-it up in cluster. Are there any tutorials that you can recommend?

Thanks
