All nodes show unknown health, and I can't see any status for any roles due
to error "Internal error while querying the Host Monitor".
How to fix this? I'm pretty new to CDH and Hadoop, so I don't know which
log I should show.

my /etc/hosts file for all nodes are

127.0.0.1 localhost
10.0.0.1 node1
10.0.0.2 node2
10.0.0.3 node3
10.0.0.4 node4
10.0.0.5 node5

    Additionally, when I try to add service to cluster, all the nodes shows
    health status "Good".

    The Host Monitor is a role within the CM Management Service. Can you
    confirm that it is setup and running? If it is and you are still
    seeing this problem, looking at its log and the log of the CM server
    itself -- you can get to both through the CM UI -- should help.
