debug flink in intelliJ on EMR

Hi,

I m following
https://cwiki.apache.org/confluence/display/FLINK/Remote+Debugging+of+Flink+Clusters
to
debug flink program running on EMR.

how do I specify the host in the `edit configurations` if the terminal on
emr master is
hadoop@ip-10-200-46-186
?

Thanks,
Fanbin

Hi Fanbin,

the host should be the external IP of your master node. However, usually
the port 5005 is not open in EMR (you could any other open, non-used port).

Alternatively, you could use a SSH port forwarding [1]:

ssh -L <some port>:<emr address>:5005

And then connect to localhost:<some port> in your IDE.
