| <p>By default the Trafodion authentication configuration file is located at <b><tt>$MY_SQROOT/sql/scripts/.traf_authentication_config</tt></b>. If you want to store the configuration file in a different location and/or use a different filename, then Trafodion supports environment variables to specify the alternate location/name.</p> |
| <p>Trafodion firsts checks the environment variable <b><tt>TRAFAUTH_CONFIGFILE</tt></b>. If set, the value is used as the fully qualified Trafodion authentication configuration file.</p> |
| <p>If the environment variable is not set, then Trafodion next checks the variable <b><tt>TRAFAUTH_CONFIGDIR</tt></b>. If set, the value is prepended to <b><tt>.traf_authentication_config</tt></b> and used as the Trafodion authentication file.</p> |
| <p>If neither is set, Trafodion defaults to <b><tt>$MY_SQROOT/sql/scripts/.traf_authentication_config</tt></b>.</p> |

| <blockquote><a href="http://trafodion.apache.org/">Apache Trafodion</a> is a webscale SQL-on-Hadoop solution enabling transactional or operational |
| workloads on Hadoop. <br /><br />The name "Trafodion" (the Welsh word for transactions, pronounced |
| "Tra-vod-eee-on") was chosen specifically to emphasize the differentiation that |
| Trafodion provides in closing a critical gap in the Hadoop ecosystem.<br /><br /> |
| Trafodion builds on the scalability, elasticity, and flexibility of Hadoop. Trafodion extends |
| Hadoop to provide guaranteed transactional integrity, enabling new kinds of big data |
| applications to run on Hadoop.</blockquote> |
