Subject [jira] [Commented] (HDFS-12711) deadly hdfs test
Date Fri, 17 Nov 2017 18:34:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16257363#comment-16257363

Arpit Agarwal commented on HDFS-12711:
--------------------------------------

I don't think committers are ignoring precommit run results. We usually try to rerun the failed
tests locally to check if they are related to the patch. Being a manual process, it is time
consuming and error-prone. I also don't think anyone is happy about the current situation.
Over time we have come to rely on complex MiniDFSCluster-based tests over real unit tests
and these tend to be flaky and fail in hard-to-debug ways. We probably need a community effort
to revamp our unit tests. This will also require extensive refactoring of existing classes
to make them unit-testable, a risky task in itself.
