# This script bootstraps a development environment from almost nothing; it is known to
# work on Ubuntu 16.04. It clobbers some local environment and system
# configurations, so it is best to run this in a fresh install. It also sets up the
# ~/.bashrc for the calling user and impala-config-local.sh with some environment
# variables to make Impala compile and run after this script is complete.
#
# The intended user is a person who wants to start contributing code to Impala. This
# script serves as an executable reference point for how to get started. It takes about
# two hours to complete.
#
# To run this in a Docker container:
#
#   1. Run with --privileged
#   2. Give the container a non-root sudoer wih NOPASSWD:
#      apt-get update
#      apt-get install sudo
#      adduser --disabled-password --gecos '' impdev
#      echo 'impdev ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers
#   3. Run this script as that user: su - impdev -c /bootstrap_development.sh
