Running query on INFORMATION_SCHEMA.COLUMNS

Hi,

I am trying to run following query:

SELECT table_schema, table_name, COUNT(column_name) FROM {db_name}.INFORMATION_SCHEMA.COLUMNS GROUP BY table_schema, table_name

and I am getting following error:

Error in SQL statement: AnalysisException: Catalog namespace is not supported.

com.databricks.backend.common.rpc.DatabricksExceptions$SQLExecutionException: org.apache.spark.sql.AnalysisException: Catalog namespace is not supported.

Hi @Suman Karki, can you check if UC is enabled in the advanced settings of the endpoint? Also, what DBR is your DE cluster, and what Security Mode did you choose?
