EC2 AMI 2.4/2.5 dsc20/dsc21 dependency issue - amazon-ec2

Question

I'm trying to create a 1 node Datastax community edition cluster using this guidelines on EC2 m3.xlarge (eu-west).
Here is the provided parameters:
--clustername cassandra
--totalnodes 1
--version community
As mentioned in the guideline, I opened those ports:
22
8888
1024-65355
Here is the error I found in ~/datastax_ami/ami.log:
The following packages have unmet dependencies:
dsc20 : Depends: cassandra (= 2.0.14) but 2.1.4 is to be installed

Related GitHub issue: Add support for DSC 2.2 Versions #81
Does anyone what I've done wrong.
Thanks

Answer 1

There was a bug with the dependencies - as you encountered - Add support for DSC 2.2 Versions #81 and was fixed in AMI 2.5.
Therefore be sure to use the new AMI. Do not use:
DataStax Auto-Clustering AMI
which is the AMI 2.4 version, instead use:
DataStax Auto-Clustering AMI 2.5.1-pv
or
DataStax Auto-Clustering AMI 2.5.1-hvm

Answer 2

Per the github issue:
Proposed fix committed to dev-2.5 and dev-2.6. Will test today and release today.
