Date Thu, 26 Jul 2007 21:23:31 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Lucene-hadoop Wiki" for change notification.

The following page has been changed by TomWhite:
http://wiki.apache.org/lucene-hadoop/AmazonEC2

The comment on the change is:
Add link thread other dynamic DNS providers

       * The default value for `S3_BUCKET` (`hadoop-ec2-images`) is for public images. You
normally only need to change this if you want to use a private image you have built yourself.
     
     * Hadoop cluster variables (`GROUP`, `MASTER_HOST`, `NO_INSTANCES`)
       * `GROUP` specifies the private group to run the cluster in. Typically the default
value is fine.
-      * `MASTER_HOST` is the hostname of the master node in the cluster. You need to set
this to be a hostname that you have DNS control over - it needs resetting every time a cluster
is launched. Services such as [http://www.dyndns.com/services/dns/dyndns/ DynDNS] make this
fairly easy.

       * `NO_INSTANCES` sets the number of instances in your cluster. You need to set this.
Currently Amazon limits the number of concurrent instances to 20.
