   * When you have finished, shutdown the cluster with the following:{{{
  % bin/hadoop-ec2 terminate-cluster test-cluster
  }}}
-  * Keep in mind that the master node is started first and configured, then all slaves nodes
are booted simultaneously with boot parameters pointing to the master node. Even though the
`lauch-cluster` command has returned, the whole cluster may not have yet 'booted'. You should
monitor the cluster via port 50030 to make sure all nodes are up.

     * AMI selection (`HADOOP_VERSION`, `S3_BUCKET`)
-      * When creating an AMI, `HADOOP_VERSION` is used to select which version of Hadoop
to download and install from http://www.apache.org/dist/lucene/hadoop/.
+      * When creating an AMI, `HADOOP_VERSION` is used to select which version of Hadoop
to download and install from [[http://hadoop.apache.org/common/releases.html]].
       * Change `S3_BUCKET` to be a bucket you own that you want to store the Hadoop AMI in.
     * ('''0.17''') AMI size selection (`INSTANCE_TYPE`)
       * When creating an AMI, `INSTANCE_TYPE` denotes the instance size the image will be
run on (small, large, or xlarge). Ultimately this decides if the image is `i386` or `x86_64`,
so this value is also used on cluster startup.
