Stefania commented on CASSANDRA-9961:
-------------------------------------
We still have a small issue with updating the metadata when a view is dropped
even if the pushed notification is now received [~aholmber]. It's just a matter
of updating the table metadata in addition to the keyspace views. Also, the
double {{;;}} only appears when describing a keyspace or a table, we need to
move the semi-column from {{as_cql_query()}} to {{export_as_string()}}.
Something along the lines of this diff should fix it:
