First, I have not tried it myself. However, what I have heard it has some basic SQL features so you can query you HBase table like query content on HDFS using Hive. So it is not "query a simple column", I believe you can do joins and other SQL queries. Maybe you can wrap up an EMR cluster with Hbase preconfigured and give it a try.
