New Cluster Installation

[#1]

I have installed a brand new cluster and all the services are up and running. But Ambari shows alert for all Web UIs. Here are few example :

DataNode web UI

Connection failed to http://node1.dev.XXXXXXXX.io:50075 (timed out)

Resource Manager Web UI

Connection failed to http://api1.dev.XXXXXXX.io:8088 (timed out)

Anybody has any idea on which logs Do I need to check to get more details..?

@Jay Kumar Sensharma Thanks for your reply. Looks like there were stale alerts. All the alerts went away after I restarted the ambari agents
