No interpreters available in Zeppelin

29.9k views Asked by At

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

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:

md interpreter sh interpreter, note that the interpreter name shows as 'null' sql interpreter

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

Restarting the interpreter doesn't seem to cause errors.

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.
