Subject RE: Connection timed out error while installing "Hello Samza"
Date Thu, 14 Sep 2017 19:33:26 GMT
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

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.

Hi, Anantharaman,

I just did the same steps as you described in your email and all passed on my box. Hence,
I strongly suspect that it is related to your local laptop network setup.

Could you post all the command line output when you ran the sequence of commands?
