# This script builds Impala from scratch. It is known to work on Ubuntu versions 16.04,
# 18.04, 20.04, 22.04 and 24.04. 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:
# Kerberos setup would pop up dialog boxes without this
