NTP error, waiting heartbeat error during the installation of Cloudera 6.2 agents

[#1]

Hello everyone.

When cloudera manager installs the agent on the nodes, I receive the heartbeat error. I look the log an I see this:

>>[04/Sep/2019 12:53:55 +0000] 744 Monitor-HostMonitor throttling_logger ERROR ntpq: ntpq -np: not synchronized to any server

All host can see the others, the Cloudera Server host has ntp configured, and if I execute ntpq -np on the client where I try to install the agent, it runs and ntp is working.

Could anyone help me?

Thanks

Well, I've found a solution. I install a DNS server on the main node, and now the cluster is working.
