> For checking gmond's on remote hosts we need open TCP port. By default these ports are
opened, but they were opened by IPv6 protocol only (see configs /etc/ganglia/hdp/HDPJobTracker/gmond.core.conf
for example).
> So, if we want open these ports in IPv4, we will override tcp_accept_channel property
in /etc/ganglia/hdp/HDPJobTracker/conf.d/gmond.slave.conf (for example) with FQDN of host
(except host with master components).
