-----------------------------------------
Component/s: (was: Legacy/CQL)
Tool/cqlsh
> cqlsh cannot describe keyspace when having table schema extensions
> ------------------------------------------------------------------
>
> Key: CASSANDRA-14942
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14942
> Project: Cassandra
> Issue Type: Bug
> Components: Tool/cqlsh
> Environment: Cassandra 3.11.3
> The issue comes from the cqlsh utility, in cassandra/metadata.py, function
> _all_as_cql, viewkeys is not known.
>
>
> Reporter: vincent royer
> Priority: Minor
> Labels: cqlsh
>
> When adding a schema table extension to a table, cqlsh failed to describe
> keyspace or table with the following error message: 'module' object has no
> attribute 'viewkeys'
> Step to reproduce the issue:
> {{docker run --name some-cassandra -d docker.io/cassandra:3.11.3}}{{docker
> exec -it <container_id> cqlsh <<EOF}}
> {{CREATE KEYSPACE ks WITH replication = \{'class': 'SimpleStrategy',
> 'replication_factor': 1};}}
> {{CREATE TABLE ks.cf (id text PRIMARY KEY , a int);}}
> {{INSERT INTO system_schema.tables (keyspace_name, table_name, extensions )
> VALUES ( 'ks','cf',\{'key1':textAsBlob('foo')});}}
> {{EOF}}
>
> {{docker exec -it <container_id> cqlsh -e "DESC KEYSPACE ks"}}
> {{'module' object has no attribute 'viewkeys'}}
>
> docker exec -it c75a002959e2 cqlsh --debug -e "DESC KEYSPACE ks"
