------------------------------------
Labels: aws-ec2 (was: )
> AWS CentOS marketplace AMI misdetecting OS type
> -----------------------------------------------
>
> Key: JCLOUDS-1351
> URL: https://issues.apache.org/jira/browse/JCLOUDS-1351
> Project: jclouds
> Issue Type: Bug
> Components: jclouds-compute
> Affects Versions: 2.0.2
> Reporter: Richard Downer
> Priority: Minor
> Labels: aws-ec2
> Fix For: 2.1.0
>
>
> When jclouds encounters an official CentOS Linux AMI from the AWS Marketplace, it detects the operating system as "unrecognized".
> To reproduce, set the {{jclouds.ec2.ami-query}} / {{jclouds.ec2.cc-ami-query}} properties to search the AWS Marketplace for CentOS images. Example: {{owner-id=679593333241;state=available;image-type=machine;root-device-type=ebs;architecture=x86_64;virtualization-type=hvm;name=CentOS Linux *}}
> jclouds will discover from AWS AMIs such as this one:
> {code:xml}
> <item>
> <imageId>ami-061b1560</imageId>
> <imageLocation>aws-marketplace/CentOS Linux 7 x86_64 HVM EBS 1704_01-b7ee8a69-ee97-4a49-9e68-afaee216db2e-ami-d52f5bc3.4</imageLocation>

> if (in.toLowerCase().replaceAll("\\s", "").indexOf(os.toString()) != -1) {
> myOs = os;
> }
> }
> return myOs != null ? myOs : OsFamily.UNRECOGNIZED;
> }
> {code}
> This enumerates over the known OS names to see if there's a match in the AMI name. The string {{CentOS Linux 7 x86_64 HVM EBS 1704_01-b7ee8a69-ee97-4a49-9e68-afaee216db2e-ami-d52f5bc3.4}} contains matches two enum values: *CENTOS* and *LINUX*. It seems that the alphabetically-last value is the one that is selected, so that this method returns LINUX and not CENTOS.
