Summary: Make pip_download.py interruptible
Key: IMPALA-13585
URL: https://issues.apache.org/jira/browse/IMPALA-13585
Project: IMPALA
Issue Type: Improvement
Components: Infrastructure
Reporter: Riza Suminto
infra/python/deps/pip_download.py use multiprocessing.pool.ThreadPool where
each thread calls wget. It is also wrap the download_package function with
retry wrapper. When there is a network issue happen, pressing Ctrl+C does not
immediately terminate pip_download.py and all its children. It should be
possible to capture SIGINT and pass it as cancellation event to all threads.
