Yes, I can do that, but I would want to connect to my interpreter via
any Zeppelin instance, not only via one customised, with an additional
interpreter added to its sources at compile time. This is why I wanted
to use a remote interpreter, i.e. one in an independent application.
This constructor:
RemoteInterpreterServer interpreter=new
RemoteInterpreterServer("localhost",
RemoteInterpreterUtils.findRandomAvailablePortOnAllLocalInterfaces(),
":", "groupId", true);
works only with isTest=true, which I guess is for ... testing only.
But I do not know, there are no docs.
If the remote interpreter does not work, I will modify some simple
interpreter to support a remote interpreter. I guess that it would
work, but it seems somewhat nonsensical to implement a functionality
which in theory is already provided by Zeppelin.
