[SPARK-5078] Optionally read from SPARK_LOCAL_HOSTNAME
Current spark lets you set the ip address using SPARK_LOCAL_IP, but then
this is given to akka after doing a reverse DNS lookup. This makes it difficult
to run spark in Docker. You can already change the hostname that is used
programmatically, but it would be nice to be able to do this with an
environment variable as well.
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/marmbrus/spark localHostnameEnv
