Overview

Lingual is true SQL for Cascading and Apache Hadoop.

Lingual includes JDBC Drivers, SQL command shell, and a catalog manager for creating schemas and tables.

Lingual is still under active development under the wip-1.0 branch. Thus all wip releases are made available from the files.concurrentinc.com domain. When Lingual hits 1.0 and beyond, final releases will be under files.cascading.org.

To use Lingual, there is no installation other than the optional command line utilities.

Lingual is based on the Cascading distributed processing engine and the Optiq SQL parser and rule engine.

See the Lingual page for installation and usage.

Reporting Issues

The best way to report an issue is to add a new test to SimpleSqlPlatformTest along with the expected result set and submit a pull request on GitHub.

Failing that, feel free to open an issue on the Cascading/Ligual project site or mail the mailing list.
