> HBase-5286 changes RegionLoad writable in 94.0, making it incompatible with 92. A fix
was made in HBase-5795 where a 94 client can read response from a 92 server, but not vice
versa. Currently, if a 92 client tries to do read RegionLoad (HBase shell "status" command,
or, 92 master and 94 regionserver), it just hangs.
