Hello,
I installed apache zeppelin on a linux server that is a part of a cluster,
and I can access a browser from a different computer not directly from the
server.
When I run zeppelin, and use my computer to browse to the server on port
8080 I can see the zeppelin UI, however when I try to run paragraphs (the
simplest %md paragraph) I get a server error :
...:8080/api/notebook/interpreter/bind/{note name}When I look at the logs I can see : WARNING : A HTTP GET method, public javax.ws.rs.core.Response org.apache.zeppelin.rest.InterpreterRestApi.listInterpreter(java.lang.String), should not consume any entity. Exception : java.lang.NullPointerException thrown from the UncaughtExceptionHandler in thread "webSocketWorker-9" I thought maybe I should have used the port 8081 of the webSocket (which I still don't fully understand its meaning and when to use it), but it gives an empty response. I thought maybe there is a problem with the specific 8081 port on the server so I changed the configuration of the port to 8079 (therefore the webSocket should be on 8080). However, browsing to the server on port 8080 returns an empty response (and the browsing to 8079 results the same as before for 8080). This means the port isn't the problem. Can you help me understand what am I doing wrong? Should I use the websocket? if I should why it doesn't work? Should I stick to the zeppelin UI on port 8080? If I should, why can't I run paragraphs? Thanks
