Laxman commented on LENS-123:
-----------------------------
+1 on non-configuration based approach. imho, additional configuration looks
overweight.
I can compare this exactly to FileSystem object of hadoop. A key-based factory
pattern approach should be sufficient. Like hadoop's
[FileSystem.get|https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileSystem.java]
method.

> Currently we are loading only one driver instance per class. We should be
> able to load multiple different instances of a driver class.
> For example, There can be multiple HiveDrivers talking to different
> HiveServers sitting on each colo. Or different JDBCDrivers talking to
> different dbs.
