Talk:Hadoop Virtual Cluster Appliance
From Grid-Appliance Wiki
The potential for out-of-sync software appears at
http://www.grid-appliance.org/wiki/index.php/Hadoop_Virtual_Cluster_Appliance
under Installing the hadoop package. Step 4 states 'Repeat the above steps for all the nodes you want in the virtual cluster. ...'.
If the software at http://archive.canonical.com/ is updated at the wrong time this procedure will cause sync problems. Instead the software should be downloaded just once.
Have you experienced any issues? I can't imagine machines having slightly different versions of glibc or java really affecting Hadoop.
