RE: Questions about Hive
Regarding usage of APIs to work on HIVE, here is a tip:

Try using a JDBC connector (like 'hive-jdbc-0.7.1-cdh3u1.jar') as a
plugin in any querying tool such as DbVisualizer.

I am connecting to hive using the above setup as well as using SQL
Explorer plugin in Eclipse.

Note:  I am a newbie to Hive.

Can someone please answer the following questions?

1)  Does Hive provide APIs (like HBase does) that can be used to
retrieve data from the tables in Hive from a Java program?  I heard
somewhere that the data can be accessed with JDBC (style) APIs.  True?

2)  I don't see how I can add indexes on the tables, so does that mean a
query such as the following will trigger a MR job that will search files
on HDFS sequentially?
hive> SELECT a.foo FROM invites a WHERE a.ds='2008-08-15';
3)  Has anyone compared performance of Hive against other NOSQL
databases such as HBase, MongoDB.  I understand it's not exactly apples
to apples comparison, but still...
