---------------------------------------
Summary: Disable function CARDINALITY in grammar
Key: DRILL-2115
URL: https://issues.apache.org/jira/browse/DRILL-2115
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Affects Versions: 0.8.0
Reporter: Victoria Markman
Assignee: Jinfeng Ni
Priority: Minor
Since we don't support multiset type, we should disable CARDINALITY function as
well:
{code}
0: jdbc:drill:schema=dfs> select cardinality(list) from `test.json`;
Query failed: Query stopped., Failure while trying to materialize incoming
schema. Errors:
Error in expression at index -1. Error: Missing function implementation:
[cardinality(BIGINT-REPEATED)]. Full expression: --UNKNOWN EXPRESSION--.. [

Error: exception while executing query: Failure while executing query.
