Hi,
We would like to launch the Interpreter on a different host than the host
on which Zeppelin server is running. We found this link which tells us it
is possible:
I see that it launches the interpreter.sh script and specified the dir to
the interpreter along with a port number in RemoteInterpreterProcess.java.
As a quick test tried to change code in reference() in the
RemoteInterpreterProcess.java from "localhost" to a different host name but
get Connection refused exception ..see below: Pls advise on how we can
enable the launch of the Interpreter process on a different host. Thanks.
