title: Can't open shared library '/usr/lib/mysql/plugin/ha_cassandra.so'
body: <p>I can't install the <strong>cassandra</strong> plugin in <strong>mariadb 10.0.20</strong>, 
  I tried with this:</p>
  
  <pre><code>MariaDB [(none)]&gt; INSTALL PLUGIN cassandra SONAME 'ha_cassandra.so';
  </code></pre>
  
  <blockquote>
    <p>ERROR 1126 (HY000): Can't open shared library
    '/usr/lib/mysql/plugin/ha_cassandra.so' (errno: 2, cannot open shared
    object file: No such file or directory)</p>

  <pre><code>MariaDB [(none)]&gt; INSTALL SONAME 'ha_cassandra.so';
  </code></pre>
