Description

An end-user SQL client tool (ie in the screenshot) can list tables from hiveserver2 and major DBs (Mysql, postgres,oracle, MSSQL..etc). But with SparkSQL it does not display any tables. This would be very convenient for users.

This is the exception in the client tool (Aqua Data Studio):
