AWS unreachable error when executing Metron Installer

gvetticaden1 — Thu, 24 Mar 2016 15:58:11 GMT

I'm following the instructions for installing Metron here: https://github.com/apache/incubator-metron/tree/master/deployment/amazon-ec2

In the ansible.log, I'm seeing the following error during the ansible [Setup] task:

How do I resolve this?

This is primarly caused because the path to the metron code is too long. You can solve this problem by shortening the path or changing the control_path

from

control_path = %(directory)s/%%h-%%p-%%r

control_path = %(directory)s/%%C

You may also see those types of errors present as:

SSH Error: unix_listener: "/really/long/path/hostname.tempcharacters" too long for Unix domain socket

Same fix as above, shorten the path to your deployment scripts or modify the control_path in ansible.cfg as @George Vetticaden indicated above. in

Also incase anyone else comes across this, the file you need to modify from the root of your metron dir is:

./deployment/amazon-ec2/ansible.cfg
