<h1 id="install">Install</h1>
<p>The following steps installs a Trafodion evaluation on a 64-bit RHEL/CentOS Hadoop environment running on of the following Hadoop distributions:</p>
</div>
<div class="section">
<h2 id="Prerequisites">Prerequisites</h2>
<p>Trafodion is installed as an add-on to an existing Hadoop environment. Currently, one of the following Hadoop distributions is <b>required</b>:</p>
<ul>
<li>Cloudera CDH 5.2</li>
<li>Cloudera CDH 5.3</li>
<li>Hortonworks HDP 2.2</li>
</ul>
<p>The following Hadoop services <b>must be</b> in a STARTED state and fully functional.</p>
<ul>
<li>HDFS</li>
<li>YARN with MRv2</li>
<li>ZooKeeper</li>
<li>HBase</li>
<li>Hive (optional)</li>
</ul>
</div>
<div class="section">
<h2 id="Create_Provisioning_User">Create Provisioning User</h2>
<p>Create a Linux user on the Hadoop system that you’re installing Trafodion on with the following characteristics:</p>
<ul>
<li>Privileges to run <b><tt>sudo</tt></b> with <b><tt>root</tt></b> access levels.</li>
<li>Passwordless ssh access from the Provisioning Node to all other nodes in the cluster.</li>
<li>Not named <b><tt>trafodion</tt></b>.</li>
</ul>
<p>Perform the remaining steps in this procedure using the Provisioning User.</p>
</div>
<div class="section">
<h2 id="Download_Binaries">Download Binaries</h2>
<p>Download all binaries listed above except the <b>Trafodion Clients</b> into a diretory of your choosing</p>
<p><b>Example</b></p>
<div class="source">
<div class="source">
<pre>mkdir $HOME/trafodion
mkdir $HOME/trafodion/downloads
cd $HOME/trafodion/downloads
wget &lt;log4c++ RPM&gt;
wget &lt;Trafodion Installer&gt;
wget &lt;Trafodion Server&gt;
</pre>
</div>
</div>
</div>
<div class="section">
<h2 id="Install_log4c">Install log4c++</h2>
<p>Use <b><tt>yum install</tt></b> to install the <tt>log4c++</tt> RPM on all nodes on all nodes in your Hadoop cluster.</p>
</div>
<div class="section">
<h2 id="Unpack_Trafodion_Installer">Unpack Trafodion Installer</h2>
<p>Use <b><tt>tar -zxf</tt></b> to unpack the Trafodion Installer.</p>
<p><b>Example</b></p>
<div class="source">
<div class="source">
<pre>cd $HOME/trafodion/downloads
tar -zxf apache-trafodion-installer-1.3.0-incubating-bin.tar.gz -C $HOME/trafodion
</pre>
</div>
</div>
</div>
<div class="section">
<h2 id="Create_Configuration_File">Create Configuration File</h2>
<p>The Trafodion Installer uses a configuration file that describes your Hadoop environment.</p>
<p><b>Copy Configuration Template File</b></p>
<div class="source">
<div class="source">
<pre>cd $HOME/trafodion/installer
cp trafodion_config_default my_config
</pre>
</div>

</div>
<div class="section">
<h2 id="Run_trafodion_install">Run <tt>trafodion_install</tt></h2>
<p>You’ll use the Trafodion Installer (<b><tt>trafodion_install</tt></b>) to create the Trafodion Runtime User (<b><tt>trafodion</tt></b>), modify your system and Hadoop environment, restart ZooKeeper, HDFS, and HBAse to activate configuration changes, and install/starts Trafodion.</p>
<p><b>Example</b></p>
<div class="source">
<div class="source">
<pre>cd $HOME/trafodion/installer
./trafodion_install --accept_license --config_file my_config
</pre>
</div>
</div>
<p>The Trafodion Installer performs all the operations required to install and start Trafodion. Type <b><tt>initialize trafodion;</tt></b> when the <b><tt>trafci</tt></b> prompt (<b><tt>&gt;&gt;</tt></b>) appears.</p>
<p><b>Example</b></p>
<div class="source">
<div class="source">
<pre>Apache Trafodion Conversational Interface 1.3.0

</div>
</div>
</div>
<div class="section">
<h2 id="Verify_Installation">Verify Installation</h2>
<p>Perform this step as the <b><tt>trafodion</tt></b> user.</p>
<p>First, check the status of the Trafodion environment.</p>
<p><b>Example</b></p>
<div class="source">
<div class="source">
<pre>sudo su trafodion
swstatus
</pre>
</div>
</div>
<p>Second, run a simple smoke test using <b><tt>sqlci</tt></b>. Use the following commands:</p>
<div class="source">
<div class="source">
<pre>sqlci
&gt;&gt; get schemas;
&gt;&gt; create table table1 (a int);
&gt;&gt; invoke table1;
&gt;&gt; insert into table1 values (1), (2), (3), (4);
&gt;&gt; select * from table1;
&gt;&gt; drop table table1;
&gt;&gt; exit;
</pre>
</div>

<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 &quot;Trafodion&quot; (the Welsh word for transactions, pronounced
&quot;Tra-vod-eee-on&quot;) 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>

Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making
process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the
completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.</span>
