GetSolr NoClassDefFoundError
Hello,
I'm trying out my first dataflow using NiFi. The flow involves GetSolr ->
LogAttributes. I ran into NoClassDefFoundError while trying this.
Here is an extract from nifi-app.log
18:36:26 EDTERROR7a7692b6-a9dd-4a95-a68a-932d54774144

Should I be manually adding certain jars to class path?
A more general question, how are jars built, distributed and loaded in
NiFi.
Asking this mainly because of the extendable design of this project.
I have to say it was super easy to get started with NiFi. Doc was well
organized.
I had my first visit to NiFi page y'day morning and I'm writing my first
dataflow today evening...hit my first exception too!!
Regards,
Srikanth

You arent doing anything wrong. We introduced a regression with the solr
processors. It will be resolved in the upcoming 030 release. It is in
testing so vote shall be soon.
Thanks

Srikanth/Joe,
The NoClassDefFoundError was a side effect that resulted when we bumped
several dependencies to newer versions in the 0.2.x release, specifically
the httpclient. We have the fix ready to go for 0.3.0, the Jira is -
https://issues.apache.org/jira/browse/NIFI-780

Hello Srikanth,
Nope you should not have to mess with the classpath for that to work.
Created a JIRA for it [1].
Can you provide a bit about your config on GetSolr?
Regarding the extension and class loader model the developer guide
does a pretty good job of describing it [2]. You can get to those
docs from from the site [3] or a running instance of NiFi.
Thanks
Joe
