Recently I installed Zeppelin from git using mvn clean package -Pspark-1.5 -Dspark.version=1.5.1 -Phadoop-2.4 -Pyarn -Ppyspark -DskipTests and I can't run the tutorial because of this error:
java.net.ConnectException
Any idea why this is happening? I haven't modified any of the conf files because I am interested in running it using the embedded Spark binaries.
I already check most of the threads here and none of them has worked.
Thanks
EDIT: I am using a Mac
Apache Zeppelin uses multi-process architecture, where ZeppelinServer process communicates with InterpreterGroup process though Apache Thrift API
This error usually indicates that ZeppelinServer process can not reach Interpreter process, running on same machine due to abnormal executor termination of the latter.
More details can be found in Interpreter process logs ./logs/zeppelin-interpreter-<interpreter name>-<username>-<hostname>.log and ZeppelinServer process logs under ./logs/zeppelin-<username>-<hostname>.log

I am trying to install flink on windows running into all sorts of problems . Please help.
Downloading the tar file from net, does not give me windows bat file options. Used the download links at https://flink.apache.org/downloads.html#apache-flink-1111. So i cannot run start-local.bat. Infact i dont even have start-local.sh . I ended up installing cygwin just so i can run start cluster bat
However running the start cluster bat is giving weird issues and exiting immediately.
$ ./start-cluster.sh
Starting cluster.
Starting standalonesession daemon on host DESKTOP**.
Starting taskexecutor daemon on host DESKTOP**.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Improperly specified VM option 'MaxMetaspaceSize=268435456

This is an open bug for sometime and is deferred to Flink 1.14 version.

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:
[ssh-agent] Looking for ssh-agent implementation... Could not find
ssh-agent: IOException: Cannot run program "ssh-agent": CreateProcess
error=2, The system cannot find the file specified Check if ssh-agent
is installed and in PATH [ssh-agent] FATAL: Could not find a suitable
ssh-agent provider
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!
flink run /home/admin/Documents/flink_cep/Flink-master/dist/Kinesis.jar
When I am trying to run Jar file in command line, getting error but my code is running fine in Netbeans IDE:
A NoSuchMethodError indicates a version conflict.
You should verify that you compiled your Flink job with the same Flink version as your cluster is running.
I am unable to run flink (1.0.3) process in zepplin. It is pending and web ui is not recording the process: both in cluster and local mode. Flink itself works fine in command line and intellij. I built zeppelin as mvn clean package.
Has anyone had a similar issue? Do I need to amend zeppelin-env.sh to rectify filk? I am unable to kill process in zeppelin web ui had to use ./bin/zeppelin-daemon.sh restart
I am using Flink 1.2 but I had the same problem.
I did two thing and it worked for me.
First of all, update your version. After, in the Interpreter I changed the value host = local to your localhost IP address.
Second, kill all the procces of Flink in terminal, just use web ui of Zeppelin.
You can check everything is going fine writting:
%flink
senv
res0: org.apache.flink.streaming.api.scala.StreamExecutionEnvironment = org.apache.flink.streaming.api.scala.StreamExecutionEnvironment#48388d9f
Let me know how it is going.
Regards! :)
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
