Example 1 with DescribeMountTargetsResult

use of com.amazonaws.services.elasticfilesystem.model.DescribeMountTargetsResult in project cloudbreak by hortonworks.

the class AwsEfsResourceBuilder method delete.

    // To delete an EFS instance, need the following steps
    // 1. Terminate the EC2 instances that mount on this EFS. The caller of this function has to make sure it is done before calling this function
    // 2. Delete the mount targets of this EFS.
    // 3. (Optional) Delete the security group of each mount target. AWS does not charge for security groups
    // 4. (Optional) Delete the security group of the EC2 instances at step 1. The mount target's security group has a rule that references
    // the EC2 security group. Therefore, we cannot first delete the EC2 instance's security group.
    // 5. Actually delete the EFS
    //
