Subject Re: Hive ODBC driver - Cloudera not contributing
Date Fri, 02 Dec 2011 21:22:46 GMT
Hi Li,

The Cloudera ODBC driver for Apache Hive is free to use, and anyone can
download it from the Cloudera support site:

> 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.
