I installed HDP with 1 Ambari server and 2 nodes. After all VM restart I restarted ambari-server and ambari-agent (each nodes)
I logged to Ambari UI but I have a status "datanodes 0/2 started"
Thanks for your help
Some more info ...
ambari-server IP : 192.168.0.7 / ambari-node-1 : 192.168.0.3 / ambari-node-1 : 192.168.0.4
netstat -nputw on ambari-server
tcp6 0 0 192.168.0.7:8441 192.168.0.3:53747 ESTABLISHED 1593/java .... tcp6 0 0 192.168.0.7:8441 192.168.0.4:48140 ESTABLISHED 1593/java
So coonection seems established beetween server and 2 agents

Thanks for your Help
Issue resolved. I share the solution ...
The pb was due to missconfiguration on datanode /etc/hosts after reboot. node2 cannot connect to node1 via FQDN
It's an important point (not clear in the doc). All nodes ambari server and data must be able to connect each other
