----------------------------------
Hi [~laszlog] , thanks a lot for your reply, I have some doubts about your
comments:
# I didn't flip the default behavior, when user doesn't set the
'PREPOPULATE_M2_REPOSITORY' env variable, the bootstrap_system.sh will also
download because of the bash grammar '${PREPOPULATE_M2_REPOSITORY:-true}'.
# This env variable was added to the bootstrap_system.sh, it only affects the
bootstrap_system.sh but buildall.sh, and the bootstrap_system.sh will be
executed before buildall.sh.
# Personally I don't like 'suppression-type' flag, because it is
counterintuitive. there is another true or false flag named
DOWNLOAD_CDH_COMPONENTS, so the naming rule in impala was not consistent. But
this is not a key problem, I can change it if most people like the
'suppression-type'.
Thanks for your reply again, and I'm looking forward to your final reply. :D

> Project: IMPALA
> Issue Type: Improvement
> Affects Versions: Impala 4.1.0
> Reporter: yx91490
> Assignee: yx91490
> Priority: Major
>
> Currently bootstrap_system.sh will prepopulate the .m2 directory by download
> a 800M+ archive file from jenkins.impala.io, this intended to speed up the
> maven package process, so it's not required. meanwhile, due to different
> network environment, the download speed of the archive file is not
> necessarily fast.
> I want to add an environment variable 'PREPOPULATE_M2_REPOSITORY' to control
> whether to prepopulate the m2 directory or not.
