Subject Re: cant connect to zookeeper on ec2
Date Sun, 24 May 2015 03:08:36 GMT
Thanks David. What do the second and fourth lines do? The first line
opens all the tcp port for the security group sg-38391c52, right?
Maybe you can start by opening up all the tcp ports for 0.0.0.0/0 and
see if that works.
