# This script builds Impala from scratch. It is known to work on Ubuntu 16.04. To run it
# you need to have:
#
# 1. At least 8GB of free disk space
# 4. A connection to the internet (parts of the build download dependencies)
#
# To bootstrap a more complete development environment that includes not only building
# Impala but also running and testing it, see bootstrap_development.sh in this directory.

# Set up some logging and exit conditions:
set -euxo pipefail

# Install non-java dependencies:
sudo apt-get update
sudo apt-get --yes install g++ gcc git libsasl2-dev libssl-dev make \
    python-dev python-setuptools libffi-dev libkrb5-dev
