Description

The HiveServer1 driver does not adhere to the JDBC standard of returning null when it can't handle a connection URL. It instead throws an exception which leads to subsequent exceptions (from other drivers, i.e. the HiveServer2 one) being swallowed.

This is what you'd see:

Error: Invalid URL: jdbc:hive2://localhost:10000/default;principal=hive/[e-mail] (state=08S01,code=0)
java.sql.SQLException: Invalid URL: jdbc:hive2://localhost:10000/default;principal=hive/[e-mail]
at org.apache.hadoop.hive.jdbc.HiveConnection.<init>(HiveConnection.java:86)

In addition this patch cleans up the drivers a bit.
