I just started up full dev from the 0.4.2 release tag, and ended up with failed heartbeats for all my services in ambari. After investigation, I found the my /etc/hosts ( on node1 ) had multiple entries for node1 :
[vagrant@node1 ~]$ cat /etc/hosts 127.0.0.1 node1 node1 127.0.0.1 localhost ## vagrant-hostmanager-start 192.168.66.121 node1 ## vagrant-hostmanager-end After removing the 127.0.0.1 node1 node1 line and restarting the machine + all the services etc my issues are resolved and my board is green. I am not sure why this may happen. Hopefully if you are seeing this, this will help. Anyone know why this may happen? ottO
