Currently I’m using Scientific Linux6 what should be a modified RHEL6.
When I’m doing the web based install, after the second step, my nodes are installed but not registered.
I can see 2 things in the log file:
22:14:14,113 WARN HeartBeatHandler:331 – Received registration request from host with non matching os type, hostname=master, serverOsType=redhat6, agentOstype=scientific6
( This is funny, because ALL my servers, also the ambari server are the same scientific6 images)
But the real problem is maybe this:
22:36:36,982 WARN nio:651 – javax.net.ssl.SSLException: Received fatal alert: unknown_ca
22:36:44,687 WARN nio:651 – javax.net.ssl.SSLHandshakeException: null cert chain
22:36:45,034 WARN nio:651 – javax.net.ssl.SSLProtocolException: handshake alert: no_certificate
All my servers hase the same hosts file, with fix IP-name pairs. Ping works for everywhere. Also password-less ssh with root.
