> There is no DNS in some real cluster network.
> When we create a HiveClient in a Gateway machine, and submit a sql for
> HiveonSpark, then
> 1. the HiveClient will spark-submit a RemoteDriver class to YARN cluster,
> with args --remote-host which value is the Gateway hostname
> 2. the RemoteDriver which run on one slave of the YARN cluster, and it will
> connect to Gateway use the value of arg(--remote-host)
> 3. if the slave do not resolve the Gateway hostname(no DNS)，it will connect
> failed
> So, we can use ip of the Gateway for the --remote-host , and the slave can
> use ip to connect Hive Client on the Gateway
