Description

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:3.11.3docker 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"
