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 On Fri, Apr 26, 2024 at 3:33 PM Biao Geng <biaoge...@gmail.com> wrote: > Hi Hemi, > How do you start your flink cluster?
