we keep getting this issue when installing zeppelin solr from scratch. this happens after following the steps mentioned on the readme, and then trying to create a notebook and running the "list" command

On further investigation I see this exception in the interpreter log: Caused by: java.lang.ClassNotFoundException: com.lucidworks.zeppelin.solr.SolrInterpreter at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:338) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at org.apache.zeppelin.interpreter.remote.RemoteInterpreterServer.createInterpreter(RemoteInterpreterServer.java:301)

can any anyone help me in understanding what am I doing wrong here ?

aroopganguly commented 6 years ago

@kiranchitturi would you please advise ?

aroopganguly commented 6 years ago

I was able to get around this issue by adding com.lucidworks.zeppelin:zeppelin-solr:0.0.1-beta as an artifact while creating the interpreter.

aroopganguly commented 6 years ago

it would be good though to understand why it does not work as advertised on the readme though.

Hi @aroopganguly. Apologies for being inactive for a while.

I have looked into this installation issue and replicated with 0.8.0 version. The command works fine with 0.7.x. Looks like the problem is with the interpreter name, the command I had in README used zeppelin-solr instead of solr and that caused 0.8.0 to fail for some reason. I will fix the README

 ./bin/install-interpreter.sh --name solr --artifact com.lucidworks.zeppelin:zeppelin-solr:0.0.1-beta2
