Unassign a region. Unassign will close region in current location and then
reopen it again.  Pass 'true' to force the unassignment ('force' will clear
all in-memory state in master before the reassign).  Use with caution.  For
expert use only.  Examples:

  hbase> unassign 'REGIONNAME'
  hbase> unassign 'REGIONNAME', true
EOF
      end

      def command(region_name, force = 'false')
        format_simple_command do
          admin.unassign(region_name, force)
        end
      end
    end
