-----------------------------------------
Summary: 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: CQL
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
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"
