I have two hosts, one with zeppelin and another where I want to run jdbc interpreter, problem is that in 0.7 I could run it like this:
<br> /opt/zeppelin/bin/interpreter.sh -d /opt/zeppelin/interpreter/jdbc -p xxxx<br>
but from 0.8 they add new parameters CALLBACK_HOST and INTP_PORT and I script throws errors:
Exception in thread "main"
java.lang.ArrayIndexOutOfBoundsException: 1
at org.apache.zeppelin.interpreter.remote.RemoteInterpreterServer.main(RemoteInterpreterServer.java:266).
Please advise how to start this interpreter with zeppelin 0.8.0 and what exactly this parameters mean because there is almost nothing on github.
Although you can find callback_host in the configuration such functionality is not available now.
The JDBC interpreter could run only on the same host as Zeppelin server.

I have been having issues getting my multibranch pipeline to perform git commands with an SSH key via the SSH Agent plugin on Windows.
I am able to successfully perform a git clone with the ssh from Git Bash on windows server that is running Jenkins.
In my pipeline log I am getting the following error when trying to use the sshagent plugin:

I have seen that installing Apache Tomcat Native libraries has helped some people, but the steps for doing so are not very descriptive.
Any help is appreciated. Thanks!
I want to ask some question about using appache-zeppelin installation.
I downloaded the zeppelin-0.5.5-incubating-bin-all
configure export JAVA_HOME=/sparkDemo/java-1.8.0-openjdk in zeppelin-env.sh and zeppelin.server.port 8084 in zeppelin-site.xml. I didn't configure SPARK_HOME in zeppelin-env.sh because i wanna use Zeppelin embedded Spark libraries.
But when i run the zeppelin tutorial code in my window browser,occur the following error: enter image description here
And even i configure SPARK_HOME, export MASTER in zeppelin-env.sh and create new interpreter in zeppelin web UI,the same error occurs.
Thanks a lot for responding me!
Stack Trace here
As mentioined in other answers, most probably the issue is that Interpreter process quite due to some error.
More details on particular error could be found in:
Interpreter process log
./logs/zeppelin-interpreter-<interpreter name>-<username>-<hostname>.log
and ZeppelinServer process log under
./logs/zeppelin-<username>-<hostname>.log
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:

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.
I am following this tutorial: https://wiki.opendaylight.org/view/Getting_started
I am trying to use the following code in opendaylight using karaf
ovs-vsctl show
But the command window says Command not found: ovs-vsctl
I have installed all the necessary libraries and the local host server (http://localhost:8181/dlux/index.html) is running fine. But somehow odl can't find ovs.
Can anyone tell me what's the error? I am running win 8.
Thank you
You need to run this command outside of karaf terminal.
Firstly, you should have ovs(Open Virtual Switch) or Mininet installed, and then create one or two open switches.
Basically, you started the SDN controller in karaf, and now in the step you are encountering problem, the switches need to be assigned ODL controller as their manager.
You must check also that ovsdb is already installed in karaf.
For that, try to execute the next command:
feature:list | grep ovsdb
That command will display all the ovsdb components/features that are available in your karaf distribution. The third column will indicate you if a given component is already installed or not (if you see an X, that means that the component is installed). If you want to install a component/feature:
feature:install <name_of_the_feature>
After that, try to execute it outside of karaf, as Sidhant01 has indicated you before.
Try to do it with sudo:
sudo ovs-vsctl show.
If you want to configure ovsdb in an active mode:
tools-vm:~$ sudo ovs-vsctl set-manager tcp:127.0.0.1:6640
tools-vm:~$ sudo ovs-vsctl show
98d8cf7a-44b1-4b02-a60c-7d832409d06f
Manager "tcp:127.0.0.1:6640"
is_connected: true
ovs_version: "2.0.2"
