debug flink in intelliJ on EMR

[Fanbin Bu]

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.
