No interpreters available in Zeppelin

Question

I have just installed the following on my Mac (Yosemite 10.10.3):

• oracle java 1.8 update 45
• scala 2.11.6
• spark 1.4 (precompiled release: http://d3kbcqa49mib13.cloudfront.net/spark-1.4.0-bin-hadoop2.6.tgz)
• zeppelin from source (https://github.com/apache/incubator-zeppelin) no additional config, just copied created zeppelin-env.sh and zeppelin-site.xml from templates. no edits.

I Followed the installation guidelines: https://zeppelin.incubator.apache.org/docs/install/install.html

I have build zeppelin without problems:

mvn clean install -DskipTests

Started it

./bin/zeppelin-daemon.sh start

Opened http://localhost:8080 and opened the Tutorial Notebook. Here is what happens when I refresh the snippets:

Here is the exception for the md interpreter in the webapp logs:

ERROR [2015-06-19 11:44:37,410] ({WebSocketWorker-8} NotebookServer.java[runParagraph]:534) - Exception from run

    at org.java_websocket.server.WebSocketServer$WebSocketWorker.run(WebSocketServer.java:657)

Restarting the interpreter doesn't seem to cause errors.

Solution

Ok I have just found the answer, at the top of the tutorial there is a snippet about interpreter binding, click the save button and all start to work normally.

I was having the same problem and resolved it based on your answer. However I didn't see a stacktrace after error. Did you do something to enable stacktrace on zepeline ui?

thanks for the soln. I had same problem. however how did you enable stacktrace on zepeline ui? I just saw ERROR in top right of paragraph with no stack trace in report section.

Clicking the save button yields me precisely the same error again. I'm using the docker variant of the tutorial mentioned in the tutorial page (zeppelin.apache.org/download.html).

@Shyam No idea about windows but there are tutorials covering that for Windows 10, maybe that would help: hernandezpaul.wordpress.com/2016/11/14/…
