Amazon EMR - Java SDK - how to get job results

I'm using Amazon EMR service to manage some big-data hive tables.
I want to know the number of items in a table from my code.
Currently I'm running a query, something like:

select count(*) from myTable;

Saving the results into a file on S3 from the EMR and then read this file from the code from S3 to get the results.

Is there a direct way to get the output of a query using the Java SDK without the need to go through S3?

I solve it by integrating with org.apache.hive:hive-jdbc.

Thanks to @ChristopherB advice.
