Tan Kim created FLINK-32900:
-------------------------------
Summary: Flink SQL doesn't find any built-in SQL functions
Key: FLINK-32900
URL: https://issues.apache.org/jira/browse/FLINK-32900
Project: Flink
Issue Type: Bug
Components: Table SQL / API, Table SQL / Planner
Reporter: Tan Kim
I wrote an app that uses a Hive-Glue catalog to run a query that joins a Hive
table with a Kafka table via the Flink Table API.
It doesn't find the REGEXP_EXTRACT function, so it tries to find the UDF in the
glue catalog.
The REGEXP_EXTRACT function is a built-in SQL function that doesn't need to
look up UDFs.
I have no idea why this is happening, is there something I'm missing?
{code:java}
Caused by: org.apache.flink.table.api.ValidationException: SQL validation
failed. Failed to get function default.REGEXP_EXTRACT{code}
