Arun Suresh updated HADOOP-11620:
---------------------------------
    Attachment: HADOOP-11620.3.patch

Updating patch to remove single port limitation. The scheme is now :
{noformat}
     kms://<PROTO>@<AUTHORITY>/<PATH>
     
     where :
     - PROTO = http or https
     - AUTHORITY = <HOSTS>[:<PORT>]
     - HOSTS = <HOST>[,<HOSTS>]
     - HOST = <HOSTNAME>[;<PORT>] // Host specific port will over-ride any
                                  // port that might be specified with ':'
     - HOSTNAME = string
     - PORT = integer
{noformat}

Also, to ensure requests from short-lived clients (keyShell etc.) do not all end up going to the same KMS, the load balancer now initializes with a random index
