> Current defaults are hardcoded 8/10 for dbcp/bonecp
> Various Connection pool managers support reading configs from a config file.
> The implementation would ideally allow end user to point Hive at the manager specific config file to let the user have full control
> HikariCP supports 
> HikariConfig config = new HikariConfig("/some/path/hikari.properties");
> see https://github.com/brettwooldridge/HikariCP
> BoneCP supports
> bonecp-config.xml
> see https://github.com/wwadge/bonecp/blob/master/bonecp/src/main/java/com/jolbox/bonecp/BoneCPConfig.java
