> Sure, sure there are other open-source options out there that aren’t Hadoop, but for example Impala 1.0 just came out...
Although Impala isn't technically Hadoop, it's daemons are co-located with each your Hadoop Data Nodes, and talks directly to HDFS and HBase. Also, there is no ETL process with Impala, you could drop a few billion row flat files into Hadoop and query it within a few minutes.
