When launching a cluster with the beta EBS scripts I'm running into the following issues:

1) Launch script is unable to mount the EBS volume due to the drive not being formatted.
- The snapshot was generated using the described method on the guide (create-formatted-snapshot).
- I manually formated the EBS volumes and was able to get past this point.

2) Scripts use hardcoded devices in the launch script that attempt to mount 2 volumes per node instead of using the JSON configuration.

3) After the nodes are up, the master cannot connect to HDFS. I opened all the correct ports via security groups, still having connection issues.

4) This is more a question than an issue. When tailing /var/log/messages on one of the slave nodes I noticed it was trying to connect to the master via public dns. Doesn't that method end up costing more for bandwidth than using the private dns / ip?
