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?. My guess Even if there are conflicts on earlier installations it should throw some other error but not the connection time out
Coming to your question " it could either related resolving "localhost" or firewall that prevents communication between ports" - how to prove it is because of Firewall issue. I am able to clone Samza files from Apache git. I can download any external files on this server ~Sri -----Original Message----- From: Navina Ramesh [mailto:nram...@linkedin.com] Sent: Thursday, September 14, 2017 2:51 PM To: dev@samza.apache.org Subject: Re: Connection timed out error while installing "Hello Samza" I wonder if this has anything to do with previous kafka / zookeeper installed on your box. Just for sanity, try clearing /tmp/zookeeeper* and /tmp/kafka* before re-trying those steps. Same as Yi, I strongly suspect issues with your local laptop setup - it could either related resolving "localhost" or firewall that prevents communication between ports.
