Hi, Anantharaman, A lot of firewall setup prevents "incoming connections", not "outgoing connections" from a box. I.e. if you are downloading files, you are establishing outgoing connections and it is fine. When you are hosting a server (i.e. ZooKeeper or Kafka), you are making an "incoming connections" to the box and will trigger the firewall rules.
Just trying to pin down the problem, could you try on a Linux box w/o any firewall rules setup and see whether that works? At least, verify that localhost resolves to 127.0.0.1 and try telnet locahost 9092 or 2181? NOTE: Success in ping simply means that you can access via ICMP, not guarantee you can establish TCP connection to the ports via firewall rules. -Yi On Thu, Sep 14, 2017 at 12:33 PM, Anantharaman, Srinatha (Contractor) < srinatha_ananthara...@comcast.com> wrote: > That is a good catch Naveena the server which I am trying to install is an > Hadoop edge node, it has kafka broker and Zookeeper client already > installed for my Hadoop > Does it matter If I am installing it on a separate folder?.
