Subject [jira] [Created] (BUILDS-102) Ability to trigger Jenkins rebuild for GitHub pull requests
Date Wed, 29 Jul 2015 10:54:04 GMT
Ismael Juma created BUILDS-102:
----------------------------------

             Summary: Ability to trigger Jenkins rebuild for GitHub pull requests
                 Key: BUILDS-102
                 URL: https://issues.apache.org/jira/browse/BUILDS-102
             Project: Infra Build Platform
          Issue Type: Improvement
          Components: Jenkins
            Reporter: Ismael Juma


It would be really useful to be able to trigger a Jenkins rebuild for a GitHub pull request
when the build fails due to a transient problem (ie flaky tests and/or environmental issues).
Despite our best efforts, it's hard to eliminate all flaky tests from the Kafka codebase (as
some are fixed, new ones appear).

This is supported by the open-source GitHub Pull Request Builder Plugin via comments in the
pull request itself (e.g. "retest this please" to rebuild, "add to whitelist" to automatically
build future pull requests from the submitter, etc.):

https://wiki.jenkins-ci.org/display/JENKINS/GitHub+pull+request+builder+plugin

Spark is using this with the AMPLab Jenkins instance:
https://github.com/apache/spark/pull/7613
https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/38199/consoleFull

The Apache Jenkins instance is using the Jenkins Enterprise GH PR plugin, which doesn't support
this functionality (probably based on https://wiki.jenkins-ci.org/display/JENKINS/GitHub+Plugin)
because the more featured one required privileges on the GitHub side that the Apache Infra
team was not able to give at the time (as explained by [~abayer]).

[~abayer] suggested that he would check if things have changed. The fact that Spark made it
work is a good indicator. We also have the option of moving to a separate Jenkins instance
(Confluent has offered theirs), but we would prefer to improve the Apache one as that benefits
the other projects too.

This was originally discussed in the following thread in the mailing list:
