Concurrent, the company behind the quite popular Java application framework for Hadoop, has released Lingual, a SQL-based DSL (ANSI SQL parser) with an execution engine optimizer built on top of Cascading:
Lingual is not going to provide sub-second response times on a petabyte of
data on a Hadoop cluster. Rather, the company’s goal is to provide the
ability to easily move applications onto Hadoop—the challenge there is
really around moving from a relational or MPP database over to Hadoop.
So it looks like not every new SQL tool around Hadoop is commercial.
