> A common pattern is to check out Impala, eg. in a Jenkins job, and then run Impala's functional python tests. If the tests are being run against a real cluster that has already been setup (as opposed to being run against the mini-cluster), it would be nice to be able to run any of our python tests without having to do a full build of Impala.
> This usually works, but occasionally gets broken eg. due to people adding imports of thrift structs to python files, since the thrift definitions aren't available without a full build. We dealt with this once recently in IMPALA-8199, and it has now cropped up again as a result of IMPALA-8158
> Going forward, I think a good solution would be to add a flag to buildall.sh, say '-testonly', that ensures that everything needed to run the python tests is done, eg. in this case something like 'make thrift-deps' should get run.
> We could incorporate running this into our pre-commit job to ensure that it doesn't get broken again in the future.
