They’re all slighly different, but keep throwing this socket.gaierror: [Errno -2] Name or service not known

Here’s what one of the tracebacks looks like:

Traceback (most recent call last):
  File "/home/ubuntu/p4-mapreduce/env/bin/mapreduce-worker", line 8, in <module>

Was hoping someone knew what I’m doing wrong. Or why this error even occurs.

I’ve tried googling, etc. but haven’t found any good documentation about this as of yet.
