[jira] [Commented] (HADOOP-16524) Automatic keystore reloading for
HttpServer2
[ https://issues.apache.org/jira/browse/HADOOP-16524?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17283896#comment-17283896 ]
Borislav Iordanov commented on HADOOP-16524:
--------------------------------------------
I looked at the failures and most pass locally. The two that didn't pass and were clearly affected by the PR are org.apache.hadoop.yarn.client.api.impl.TestTimelineClient.testTimelineClientCleanup and org.apache.hadoop.hdfs.web.TestURLConnectionFactory.testSSLFactoryCleanup. I created a new PR with fixes for those:
[https://github.com/apache/hadoop/pull/2693]
However, some of the above tests are still failing on the YARN side, plus a new HBase related failure :
org.apache.hadoop.yarn.server.timelineservice.storage.TestTimelineWriterHBaseDown
org.apache.hadoop.yarn.server.resourcemanager.security.TestDelegationTokenRenewer.testRMRestartWithExpiredToken
org.apache.hadoop.yarn.client.api.impl.TestTimelineClient.testTimelineClientCleanup
I could not reproduce any of those failures locally. Tried running from IDE or the Hadoop docker based environment. I also didn't see how they could be affected by the keystore reloading changes. So eventually I just made a cosmetic change to trigger another test run on the same PR and see what happens. Now all those tests passed, but there is a new failure:
hadoop.yarn.applications.distributedshell.TestDSTimelineV10
Seems like those are some flaky tests. Any advice how to proceed? Is it an option for the tests to be auto retried using this option [https://maven.apache.org/surefire/maven-surefire-plugin/examples/rerun-failing-tests.html] for example?
