Yongjun Zhang updated HADOOP-11045:
-----------------------------------
Description:
File this jira to introduce a tool to detect flaky tests of hadoop jenkins test
jobs. Certainly it can be adapted to projects other than hadoop.
I developed the tool on top of some initial work [~tlipcon] did. We find it
quite useful. With Todd's agreement, I'd like to push it to upstream so all of
us can share (thanks Todd for the initial work and support). I hope you find
the tool useful too.
This tool is for hadoop contributors rather than hadoop users. Thanks [~tedyu]
for the advice to put to dev-support dir.
Description of the tool:
{code}
#
# Given a jenkins test job, this script examines all runs of the job done
# within specified period of time (number of days prior to the execution
# time of this script), and reports all failed tests.
#
# The output of this script includes a section for each run that has failed
# tests, with each failed test name listed.
#
# More importantly, at the end, it outputs a summary section to list all failed
# tests within all examined runs, and indicate how many runs a same test
# failed, and sorted all failed tests by how many runs each test failed in.
#
# This way, when we see failed tests in PreCommit build, we can quickly tell
# whether a failed test is a new failure or it failed before, and it may just
# be a flaky test.
#
# Of course, to be 100% sure about the reason of a failed test, closer look
# at the failed test for the specific run is necessary.
#
{code}
How to use the tool:
{code}
Usage: determine-flaky-tests-hadoop.py [options]
Options:
-h, --help show this help message and exit
-J JENKINS_URL, --jenkins-url=JENKINS_URL
Jenkins URL
-j JOB_NAME, --job-name=JOB_NAME
Job name to look at
-n NUM_PREV_DAYS, --num-days=NUM_PREV_DAYS
Number of days to examine
