Creating a UDF Fails in elassandra though works fine in cassandra

[masumsoft]

Elassandra version: 6.2.3.7

Plugins installed: []

JVM version (java -version): 1.8.0_101

OS version (uname -a if on a Unix-like system): MacOS High Sierra 10.13.6

Description of the problem including expected versus actual behavior:

Trying to create a user defined function in elassandra throws error. It works well in cassandra 3.11.1

Steps to reproduce:

1. Run elassandra and open cqlsh
2. Create a new keyspace:

cqlsh> CREATE KEYSPACE test WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 1};
cqlsh> USE test ;

3. Create a UDF:

cqlsh:test> CREATE OR REPLACE FUNCTION fLog (input double) CALLED ON NULL INPUT RETURNS double LANGUAGE java AS 'return Double.valueOf(Math.log(input.doubleValue()));';

The above command throws the following error:

ServerError: java.lang.NoClassDefFoundError: org/objectweb/asm/ClassVisitor

Same steps works well in cassandra 3.11.1

Note that I've changed the following cassandra.yaml settings to enable UDFs:

enable_user_defined_functions: true

Yes, it's a known issue dealing with class loading. Both C* and ES use asm.jar to execute functions or scripts in a dedicated classloader, and the first who load the jar win, the second fails ! This still need some investigation, i keep the point. Thanks.

i'm getting the same. any fix update on this ? i'm running on the latest docker version of elassandra version: strapdata/elassandra:latest ELASSANDRA_VERSION=6.2.3.18

Is this possibly a Duplicate of #165?

[comdiv]

Hello is where something about this problem. We use Elassandra and has some requirements for using UDFs but cannot do anything with them

[filthz]

Any updates on this? We are affected as well

[filthz]

Are there any updates on this issue? Has this been fixed in the more recent versions?
