[jira] [Comment Edited] (CASSANDRA-7874) Validate functionality of
different JSR-223 providers in UDFs
[ https://issues.apache.org/jira/browse/CASSANDRA-7874?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14122864#comment-14122864 ]

------------------------------------------------------------------
Successfully validated these JSR-223 implementations for UDFs:
* Groovy v2.3.6
* JRuby 1.7.15
* Jython 2.5.3
* Scala 2.11.2
These JSR-223 implementations do not work:
* Clojure 1.5.1/1.6 : not working compilable script support in JSR-223 implementation
* Jaskell 1.0 : seems to be unmaintained since 7 or 8 yrs (accoring to https://java.net/projects/scripting/sources/svn/show/trunk/engines/jaskell?rev=236)
I've introduced some directories below {{lib/}} to keep scripting engine jars separate from C* jars. Directory structure is like this:
{noformat}
lib/jsr223/clojure
lib/jsr223/groovy
lib/jsr223/jaskell
lib/jsr223/jruby
lib/jsr223/jython
lib/jsr223/scala
{noformat}
Each of these directories contains a {{README.txt}} with instructions how to install those scripting engines or why they do not work.
{{cassandra.in.sh}} has been modified to scan all directories below {{lib/jsr223}} for jar files to add to C* daemon classpath.
Additionally JRuby, Jython and Scala require some system properties, which are added, if these scripting languages are detected.

> CASSANDRA-7526 introduces ability to support optional JSR-223 providers like Clojure, Jython, Groovy or JRuby.
> This ticket is about to test functionality with these providers but not to include them in C* distribution.
> Expected result is a "how to" document, wiki page or similar.
