@Simon Wang

1. For the Error "https://hdp.localdomain.localdomain.localdomain.localdomain.localdomain:8440" - Try upgrading openssl to latest version.

$yum upgrade openssl

My working openssl version is - openssl-1.0.1e-15.el6.x86_64

2. Also please modify /etc/hosts file as below - and give retry

127.0.0.1 localhost.localdomain localhost

::1 localhost.localdomain localhost

192.168.1.115 hdp
