# This is a wrapper around the 'post-review'/'rbt' tool provided by
# Review Board. This is currently used by Apache Mesos development.
#
# What does this do?
# It provides the ability to send a review for each commit on the
# current branch.
#
# Why is that useful?
# No one likes a 5000 line review request. Using this tool forces one

# This file contains environment variables required to run Spark. Copy it as
# spark-env.sh and edit that to configure Spark for your site.
#
# The following variables can be set in this file:
# - SPARK_LOCAL_IP, to set the IP address Spark binds to on this node
# - MESOS_NATIVE_LIBRARY, to point to your libmesos.so if you use Mesos
# - SPARK_JAVA_OPTS, to set node-specific JVM options for Spark. Note that
#   we recommend setting app-wide options in the application's driver program.
