> Key: HADOOP-15665

> Project: Hadoop Common
> Issue Type: Bug
> Components: precommit, yetus
> Affects Versions: 2.10.0, 3.2.0, 3.1.1, 2.9.2, 2.8.5, 2.7.8, 3.0.4
> Reporter: Kitti Nanasi

> If a patch is created with checkstyle errors, for example when a modified
> line is longer than 80 characters, then running checkstyle with the
> test-patch script runs to success (though it should fail and show an error
> about the long line).
> {code:java}
> dev-support/bin/test-patch --plugins="-checkstyle" test.patch{code}
> However it does show the error (so works correctly) when running it with the
> IDEA checkstyle plugin.
>
> I only tried it out it for patches with too long lines and wrong indentation,
> but I assume that it can be a more general problem.
> We realised this when reviewing HDFS-13217, where patch 004 has a "too long
> line" checkstyle error. In the first build for that patch, the checkstyle
> report was showing the error, but when it was ran again with the same patch,
> the error disappeared. So probably the checkstyle checking stopped working on
> trunk somewhere between April and July 2018.
