Karthik Kambatla commented on HADOOP-8649:
------------------------------------------
Found the javadoc warning. The noticed test failures seem to be due to one of
the patch's tests creating a file and not deleting it. Running all the tests
locally to make sure these issues are fixed. Will upload updated patch soon.
> ChecksumFileSystem should have an overriding implementation of
> listStatus(Path, PathFilter) for improved performance

> Currently, ChecksumFileSystem implements only listStatus(Path).
> The other form of listStatus(Path, customFilter) results in parsing the list
> twice to apply each of the filters - custom and checksum filter.
> By using a composite filter instead, we limit the parsing to once.
