Spark in DSE4.5 with EC2MultiRegionSnitch

Question

I'm have DSE 4.5 cassandra cluster with multi region data center on EC2. So i'm using EC2MultiRegionSnitch which is returning public IP. And I'm trying to create Spark node but logs says "Failed to bind PUBLIC IP:7077. I am sure it is due to EC2MultiRegionSnitch property. I spoke to Amazon guys , as they are not able to help me in binding port with public ip.

Now, I'm not sure which snitch I can use for EC2 multi region data center cluster. (apart from EC2MultiRegionSnitch). So that I'm bind cluster in multi region data center and run Spark.

Can you please suggest ??

Answer 1

The EC2MultiRegionSnitch should be fine for your setup. I suspect the issue is that port 7077 is not opened in your security group in each data center.
