Troubleshooting a host with concerning status

New Contributor

Hi everybody!

We installed CDH using Cloudera Manager on two Virtual Machines. The first one is running ok with all services, but the second shows a "Concerning Health" status and we can't even assign Data Node role to it.

Host's status page on Cloudera Manager displays the following warnings:
"
This host is in contact with Cloudera Manager. The host's Cloudera Manager Agent's software version can not be determined.
6 unknown.
Details Not enough data to test: Test of whether a host is swapping memory.
Details Not enough data to test: Test of whether a host has network frame errors
Details Not enough data to test: Test of whether the host has network interfaces that appear to be operating at less than full speed.
Details Not enough data to test: Test of whether the hostname and canonical name for this host are consistent when checked from a Java process.
Details Not enough data to test: Test of whether a host resolves DNS names in a timely manner.
Details The status of the host's NTP service could not be determined.
"

Firstly, we thought that it was a network or security problem, but we already did these tests:
- They are on same LAN;
- Ping is ok between them;
- They share same root login acess;
- Command "/etc/init.d/cloudera-scm-agent status" displays ok

Do you have any idea what could cause this problem or how could we troubleshoot it?

Thanks a lot!
