hbase region server - rolling restart

[#1]

can we include more than one region servers to restart in the rolling restart ? if not why should be the default 1 and we have option to have more than 1 in the text box

The only concern that I can think of off the top of my head is that it may affect any the latency of any application accessing HBase. If increased application latency isn't a concern, you may restart multiple RegionServers at a time.
