HDP on Linux – Installation Forum

Ambari (1.2) Installation failure

  • #15573
    David Lai

    I tried to install a fresh 3 node cluster for HDP 1.2/Ambari and performed the steps according to the Automated manual instructions till the installing, configuring deploying step,where I entered the target hosts, Ambari server ssh private key, and then click “Register and Confirm” then shortly I got the failed status in Web UI at Confirmed Hosts stage.
    I examined both log seems something related to the bad certificates in SSL connection during the Host registration.
    Below are portion of logs (too large to provided).
    Questions is what step I mis-configured or missed?

    Hi David,

    Did you try to install Ambari on clean OS? I am wondering if you had any keys already setup.

    Also, can you please make sure that resolves and reachable from the host where you pasted logs from.
