    I followed all the steps mentioned in the below article to create an Amazon EC2 cluster.


    I am stuck at the point where I have to connect to the EC2 cluster using the head node’s public DNS server. I opened all the firewalls by adding the appropriate rule for security groups. I also made sure that the firewall is not running by typing in the following commands.

    service ntpd status ; service iptables status ; service ip6tables status

    I am using windows 7 and tried all the web browsers. Please help me out. I am trying to fight this issue for the last three days. Thanks a lot.

    Hi, Aditya

    Thanks for trying HDP. I didn’t look at the instruction you followed in the orginal post. But here is our documentation:

    Please let us you your exploration.



    Linux is new to me and I guess I should brush up my basics in order to even understand your response :-) Thanks for your help though.



    Hi Aditya,

    Thanks for trying Hortonworks Data Platform. Have you also made sure that SElinux is set to “disabled”? Also, you mention that you checked the status of NTPD and iptables and ip6tables, what were the results?
