[jira] [Created] (CASSANDRA-16204) PicklingError: Can't pickle : attribute lookup video_encoding on cqlshlib.copyutil failed

["Phil Miesle (Jira)" <ji...@apache.org>]

Phil Miesle created CASSANDRA-16204:
---------------------------------------

             Summary: PicklingError: Can't pickle <class 'cqlshlib.copyutil.video_encoding'>: attribute lookup video_encoding on cqlshlib.copyutil failed
                 Key: CASSANDRA-16204
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-16204
             Project: Cassandra
          Issue Type: Bug
          Components: CQL/Interpreter
            Reporter: Phil Miesle
         Attachments: videos_by_actor.csv.gz

This seems to be a different issue than Cassandra-14982 :

$ cqlsh --version
cqlsh 6.8.0

Following Datastax Academy course DS220, in the Denormalization exercise. I received 
{code:java}
PicklingError: Can't pickle <class 'cqlshlib.copyutil.video_encoding'>: attribute lookup video_encoding on cqlshlib.copyutil failed{code}
on the COPY command into the following table:
{code:java}
CREATE TABLE videos_by_actor (
actor text,
added_date timestamp,
video_id timeuuid,
character_name text,
description text,
encoding frozen<video_encoding>,
tags set<text>,
title text,
user_id uuid,
PRIMARY KEY ( (actor), added_date, video_id )
) WITH CLUSTERING ORDER BY ( added_date desc, video_id asc);

COPY videos_by_actor(actor,added_date,video_id,character_name,description,encoding,tags,title,user_id) FROM 'videos_by_actor.csv' WITH HEADER = true{code}
Now, as it turns out my PRIMARY KEY was non-unique (noted when I failed to load as many records as were in the file), and when I changed to:
{code:java}
 PRIMARY KEY ((actor), added_date, video_id, character_name){code}
the command worked. BUT the following options also worked (though they both dropped records):
{code:java}
 WITH HEADER = true AND MINBATCHSIZE=1 AND MAXBATCHSIZE=1 AND PAGESIZE=10;{code}
and
{code:java}
 WITH HEADER = true AND NUMPROCESSES=1;{code}
So this seems to be a problem of multi-threading and user-defined TYPEs?
