Hi Li, The Cloudera ODBC driver for Apache Hive is free to use, and anyone can download it from the Cloudera support site: https://ccp.cloudera.com/display/SUPPORT/Downloads
> Why Cloudera didn't contribute to open source? > Actually, Cloudera has contributed a lot to open source and will continue to do so in the future. Over the past 18 months we have open sourced Apache Sqoop, Apache Flume, Crunch, Recordbreaker, Hue, Apache Bigtop, and Apache Whirr, and our engineers have contributed hundreds of patches to Apache Hadoop, HBase, Hive, etc. Meanwhile, we make projects like the ODBC driver and SCM Express available for free for everyone to use. > But in this case there was already Apache open source code for Hive ODBC driver and Cloudera chose not to contribute. Why? The Apache open source code for the Hive ODBC driver depends on the unixODBC driver toolkit, and consequently it inherits unixODBC's GPL license. This makes it incompatible with the ASF license. Working around this licensing problem was our primary motivation for rewriting the driver from scratch. Had this not been the case we would not have done a closed source implementation, and would have instead worked to improve the original version of the driver. Thanks. Carl
