--------------------------------------
Summary: Move impala-python initialization into the CMake build
Key: IMPALA-10274
URL: https://issues.apache.org/jira/browse/IMPALA-10274
Project: IMPALA
Issue Type: Improvement
Components: Infrastructure
Affects Versions: Impala 4.0
Reporter: Joe McDonnell
Currently, the impala-python virtualenv gets initialized on the first
invocation of bin/impala-python. Most of the time, this happens when running
bin/gen_build_version.py from buildall.sh. This is a serial part of the build,
and the virtualenv initialization takes more than two minutes.
It would be better to use ordinary python for bin/gen_build_version.py (and any
other python commands during the build) and initialize the virtualenv as a
specific step in the CMake build. This would allow the virtualenv
initialization to happen in parallel to the rest of the build, which saves
multiple minutes.
