> Currently NameNode already provides RPC calls to get its last applied
> transaction ID and most recent checkpoint's transaction ID. It can be helpful
> to provide servlets to enable querying these information through http, so
> that administrators and applications like Ambari can easily decide if a
> forced checkpoint by calling saveNamespace is necessary.
