             Summary: Spark EC2 doesn't mount local disks for i2.8xlarge instances
                 Key: SPARK-4888
                 URL: https://issues.apache.org/jira/browse/SPARK-4888
             Project: Spark
          Issue Type: Bug
          Components: EC2
    Affects Versions: 1.1.1, 1.0.2, 1.2.0
            Reporter: Josh Rosen
            Priority: Critical


When launching a cluster using {{spark-ec2}} with i8.2xlarge instances, the local disks aren't mounted.   The AWS console doesn't show the disks as mounted, either

I think that the issue is that EC2 won't auto-mount the SSDs.  We have some code that handles this for some of the {{r3*}} instance types, and I think the right fix is to extend this for {{i8}} instance types, too: https://github.com/mesos/spark-ec2/blob/v4/setup-slave.sh#L37

/cc [~adav], who originally found this issue.
