#
# Script to create a binary distribution for easy deploys of Spark.
# The distribution directory defaults to dist/ but can be overridden below.
# The distribution contains fat (assembly) jars that include the Scala library,
# so it is completely self contained.
# It does not contain source or *.class files.
#
# Arguments
#   (none): Creates dist/ directory
#      tgz: Additionally creates spark-$VERSION-bin.tar.gz
#
# Recommended deploy/testing procedure (standalone mode):
# 1) Rsync / deploy the dist/ dir to one host
# 2) cd to deploy dir; ./bin/start-master.sh
# 3) Verify master is up by visiting web page, ie http://master-ip:8080.  Note the spark:// URL.
# 4) ./bin/start-slave.sh 1 <<spark:// URL>>
# 5) MASTER="spark://my-master-ip:7077" ./spark-shell
#

# Figure out where the Spark framework is installed
