Date Thu, 14 Sep 2017 18:47:53 GMT
Yi,



Thank you for your kindly reply.



I am able to ping localhost and it is accessible.

BTW I am installing Samza on Linux server



Eagerly waiting for your help.

Hi, Ananarath,



It is very strange that you are seeing this timeout exception that we do not see. I am trying
to follow the exact steps you did to see whether there is anything broken. I will update you
this afternoon.



Meanwhile, could you check your hostname setup and firewall configuration to see whether your
local laptop has blocked access via the public IP address to your laptop? Could you verify
that your localhost is resolved to

127.0.0.1 and is accessible?
