Thejas M Nair commented on HIVE-12605:
--------------------------------------
The javadoc for the JDBC api says - "The driver shall submit a query on the
connection or use some other mechanism that positively verifies the connection
is still valid when this method is called. ".
We could use something lightweight 'read' operation to validate the connection.
Maybe a 'set <config name>' , where it just prints the value of the config name.
> Implement JDBC Connection.isValid
