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
> Add Support for Load Balancing across a group of KMS servers for HA
