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.
