It's likely you are looking for Hive PreCommit Patch Testing.
This page explains how to use parallel testing in Hive (https://issues.apache.org/jira/browse/HIVE-1487).
To use parallel tests you have to install Python with "argparse" and "mako"
modules. You can do that using your package manager or you can install the
modules by hand. If you're using Python 2.7 or newer, "argparse" module is
already included and you don't have to install it.
You can install the modules globally for all users with "easy_install":
If you don't have root acces on the machine, or you don't want to pollute your
system directories, you can install the modules in your home directory.
You'll have to update "PYTHONPATH" environmental variable to include
"~/.python_modules". You can do that by adding this line to your ".bashrc" or
Where "VERSION" is Python version you're using, like "2.6" or "2.7", for example
if you're using Python 2.6:
You will have to setup SSH so you can access all test nodes without a password.
You'll need to configure which hosts the test should run on. You should put
your configuration file in "~/.hive_ptest.conf". Configuration file format is
documented in the README file distributed with the test script.
Configuration parameter for speeding up unit tests
You can see all possible options by running:
Testing a Differential revision
If you want to test a patch from Phabricator, you
can use this command:
Testing a patch from file system
You can also test a patch from local file system.
You can provide multiple patches if you want to. They will be applied in the
same order they appear on the command line.
Multiple test runs
Multiple users can run parallel tests using the same configuration file without
problems. If you want to run different test instances simultaneously as one user you'll
have to export "HIVE_PTEST_SUFFIX" environmental variable and set it to some
unique string for each instance.
The README file
distributed with the test script explains how this variable affects the paths
defined in your configuration file.
The paths here assume you're using "~/hivetests" as your "master_base_path"; if
you are using some other path, update the paths accordingly.
After the test run ends, a test report will be generated in
"~/hivetests/report/TIMESTAMP"; the main file is named "report.html". Since
JUnit properties lists take up a lot of space, by default they are generated in
separate ".html" files and linked from "report.html". If you want to generate
just one file (for easy copying for example) you can use "--one-file-report"
switch and the properties will be embedded in "report.html". Keep in mind that
instead of getting a ~300k file, you'll get one that might be more than 10MB.
If you want to use a fixed report name instead of a timestamp, you can use
"--report-name" switch, for example:
This will generate report in "~/hivetests/report/D123". If there was already a
report with that name it will be removed.
".q.out" files from TestCliDriver and TestNegativeCliDriver runs will be copied
to "~/hivetests/report/TIMESTAMP/out" so they are available in one place.
"hive.log" files from all test runs will be copied to
"~/hivetests/report/TIMESTAMP/logs" and will be renamed to
Minimr tests (TestMinimrCliDriver, TestNegativeMinimrCliDriver and
TestHBaseMinimrCliDriver) can't run simultaneously on one machine. The script
makes sure they are not scheduled to run simultaneously on the same host during
one test run, but multiple script runs (multiple users or one user testing
multiple patches at the same time) might collide and cause failures in that test
