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:

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.

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? — nir, Aug 22 '16 at 19:42

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.

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 (http://zeppelin.apache.org/download.html). – Orco Jun 01 '18 at 00:18

@Shyam No idea about windows but there are tutorials covering that for Windows 10, maybe that would help: https://hernandezpaul.wordpress.com/2016/11/14/apache-zeppelin-installation-on-windows-10/ – Samuel Kerrien Jan 27 '19 at 17:59
