Looks like a joke. HDFS is not an FS you WANT or CAN use for VM filesystems. Its architecture is completely different from what POSIX-compliant OS wants to keep QCOW2 images (or even RAW images).
If you want fault-tolerant FS, use Ceph or Gluster or even NFS over DRBD. NFS is a stateless protocol, failover is just fine with VRRP or another shared IP option, but writeback options on the storage host can influence of course, Ceph or Gluster is a way to go.
