Subject [jira] [Commented] (HIVE-7107) Clean up HiveDrivers and fix an issue
Date Tue, 29 Jul 2014 23:12:38 GMT


Lars Francke commented on HIVE-7107:

I realize that HS1 is scheduled to be removed but I submitted this before 0.13.1 was released
and maybe 0.13.2 will be released still. Also I think there's a chance that some distributions
will keep HS1 in for a bit longer and this patch fixes an issue with it. I also don't see
any harm in maintaining code that's scheduled to be removed at some point.

> 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/_HOST@EXAMPLE.COM
> java.sql.SQLException: Invalid URL: jdbc:hive2://localhost:10000/default;principal=hive/_HOST@EXAMPLE.COM
> 	at org.apache.hadoop.hive.jdbc.HiveConnection.<init>(

> In addition this patch cleans up the drivers a bit.
