> Much of Trafodion is written in C++ and use C++ to make calls to HDFS API's.  Therefore, anyone building Trafodion must download a Hadoop version that contain native library binaries.
> Trafodion provides a convenience script, called install_local_hadoop, that sets up the Hadoop eco-system that can be used to build and test the product.   This script downloads Cloudera based versions of Hadoop and HBase.  In addition, install_local_hadoop allows you to specify a environment variable called MY_LOCAL_SW_DIST  where you can store tar files for these products.  So when you run install_local_hadoop, it gets the tar files from the location specified in MY_LOCAL_SW_DIST thereby not requiring a download from the web. 
> If MY_LOCAL_SW_DIST is not specified, install_local_hadoop downloads the files from hard coded locations.  The hard coded location for Hadoop is: http://archive.cloudera.com/cdh5/cdh/5/hadoop-2.5.0-cdh5.3.0.tar.gz. Unfortunately, this version no longer contains the native Hadoop libraries. When Trafodion is built, an error that the hdfs library is not found is returned.
> Many of the Trafodion contributors use the precreated files stored in MY_LOCAL_SW_DIST, therefore, we just cannot change the location in install_local_hadoop.  It needs to be coordinated with Trafodion contributors who use a precreated directory called MY_LOCAL_SW_DIST. 
> This JIRA has been written to resolve this issue.
