Gregory Farnum commented on HADOOP-6355:
----------------------------------------
I'm not very familiar with how issue tracking is handled here, so very
possibly. My own interest is mostly in matching the documentation and the unit
tests, though -- that's how I discovered the differences.
> Make FileSystemContractBaseTest, LocalFileSystem, and FileSystem javadoc
> compliant

> Key: HADOOP-6355
> URL: https://issues.apache.org/jira/browse/HADOOP-6355
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Reporter: Gregory Farnum
> Priority: Minor
>
> These do not all seem to play nicely together. ie, plugging the
> LocalFileSystem into FileSystemContractBaseTest (via a subclass that just
> overrides setUp to set fs=LocalFileSystem) results in 5 failures and 19
> errors out of 28 tests.
> Additionally, the unit tests expect a few undocumented behaviors (ie, it
> expects to get an IOException on mkdirs(subdir/of/a/file) rather than just
> returning false) and some contradictory behaviors (it expects that
> delete(directory, false) should succeed on an empty directory) compared to
> FileSystem's javadoc.
> I suspect that most of the fixes should come from changing the unit tests to
> be more sensible rather than modifying [Local]FileSystem, but however it's
> done these should all agree on expected behavior!
