Need help on setting up the zookeeper on my local
Hi Dev team,
I am new to open source and i want to contribute to apache zookeeper. I
need some help as some test cases are failing on my local. Can someone help
me here?
I also know about the mentorship programme of Apache. Please consider me
for a mentorship programme. Thanks in advance.
Regards,
Dinesh

I don't see the FileChangeWatcherTest.testCallbackWorksOnFileDeleted on
latest flaky build:
https://ci-hadoop.apache.org/blue/organizations/jenkins/ZooKeeper-Find-Flaky-Tests/detail/ZooKeeper-Find-Flaky-Tests/339/pipeline
It was actually flaky, but should have been already fixed: ZOOKEEPER-3219
However, the other ones, on branch 3.5, looks flaky (so probably also are
on master):
ZooKeeperServerMainTest.testReadOnlySnapshotDir
ZooKeeperServerMainTest.testReadOnlyTxnLogDir
You can try to re-run the failed tests individually:
mvn -Dtest=FileChangeWatcherTest -DfailIfNoTests=false test
If they pass you can try to re-run the whole tests again. We do have some
flaky tests, and fixes are always welcomed. Please check first if there's
already a jira ticket for it:
https://issues.apache.org/jira/browse/ZOOKEEPER-3042?jql=text%20~%20%22flaky%22
From the logs it looks like it's an issue of the multi thread test runs,
sometimes ZK instances get stuck (it's a valid question why we have ZK
instances fired up in unit tests).

Hi Dinesh,
Welcome to the ZooKeeper community, we are always happy to see interest in
the project.
Please attach logs so we can help pinpointing the problem.
You can find a lot of useful howto posts on
https://cwiki.apache.org/confluence/display/ZOOKEEPER/
Mainly:
https://cwiki.apache.org/confluence/display/ZOOKEEPER/HowToContribute
As for the mentor programme, do you mean this one:
https://community.apache.org/mentoringprogramme.html
That is more of a general programme geared toward apache contributions in
general, and there's a form to apply.
We are happy to help if you have questions, I'm not sure there will be an
assigned mentor though.
Regards,
Norbert
