> - stack advisor allocated 713m to Master and 1024m to RS, in distributed mode. For small
clusters we should default to 512m Master, RS should get as much memory as possible.
> - In distributed mode we should WARN if no DN is local and set dfs.client.read.shortcircuit
= true in ams-hbase-site if local DN is present
