Hi,
I tried using the oracle thin jdbc driver with the settings below in
hive-site.xml but got the exception pasted below[1]- anybody hit this?
(I am using Oracle 11g and hive trunk as of a month back).
Thanks,
Pradeep

Hi Pradeep,
Your config values will need to look something like this:
javax.jdo.option.ConnectionURL = jdbc:oracle:thin:@'host':'port':'db-name'
javax.jdo.option.ConnectionDriverName = oracle.jdbc.driver.OracleDriver
javax.jdo.option.ConnectionUserName </hadoop/ConnectionUserName> =
your-user-name
javax.jdo.option.ConnectionPassword </hadoop/ConnectionPassword> =
your-password
Obviously you need to replace 'host', 'port' and 'db-name' with
appropriate values. You also need to get a copy of the Oracle thin
JDBC driver (or some other JDBC driver that supports Oracle) and make
sure that it is available in Hive's classpath (e.g. by referencing it
in HIVE_AUX_JARS_PATH). If this does not work out of the box I
recommend consulting the documentation that comes with your JDBC driver.
Thanks.

Hi Pradeep,
You can check the config values for MySQL as a metastore for Hive at
the following link:
