> for the query like select 1, select current_timestamp, select current_date
> hive retrieve all the Materialized view from megastore, if the no of databases are too large then this call take lots of time, the situation becomes worse if there are too frequent if hive server receives frequent "select 1" query ( connection pool uses it to check if the connection is valid or not).
