title: Can't get Sqoop 1.99.3 working with Apache Hadoop 2.4.0 on 64 bit Centos 6.5
body: <p>I have Apache hadoop working and installed on Centos 6.5 KVM virual server. It is installed at</p>
  
  <pre><code>/home/hduser/yarn/hadoop-2.4.0 and the config files are in /home/hduser/yarn/hadoop-2.4.0/etc/hadoop.
  </code></pre>
  
  <p>I was getting complaints from hadoop about the libraries being 32 bit (guess the binary installation contains these by default) so I did a complete source build to get the 64 bit libs. But it seems sqoop 1.99.3 will only want use the hadoop jars anyway..(?)</p>
  
  <p>This is the main error it seems and it seems a popular one too but I can't find any suggestions that work. addtowar.sh is not present in my sqoop installation</p>
