> Hive Metastore uses the 'HikariCP' database connection pool. The default
> number of connections to the database is 10. For the Qtests, connecting to a
> local DerbyDB, there need not be more than 4 connections. Anymore simply adds
> undo overhead and by looking at the QTest logs, I see a bunch of 'connection
> refused' from HikariCP. It may be the case that the standalone DB does not
> support that many concurrent connections anyway.
