Hi Yuan/Jian I was going through your following blueprint. http://tracker.ceph.com/projects/ceph/wiki/Hadoop_over_Ceph_RGW_status_update This is very interesting. I have some query though. 1. Did you guys benchmark RGW + S3 interface integrated with Hadoop. This should work as is today. Are you seeing some shortcomings with this solution other than localization ? 2. The only advantage with your solution is to get locality with RGW proxy ? Or there are other advantages as well ? 3. Hadoop with CephFs is the preferred solution from RedHat. Are you going to benchmark your solution against this as well ?
