Doug Cutting commented on HADOOP-2754:
--------------------------------------
> Doug, do you mind if I open a new jira on this idea?
I think composition is required to fix this issue. listStatus(Path,
PathFilter) when applied to a CheckSumFileSystem should filter both for .crc
files and for the user-specified PathFilter. That means something like:
{noformat}
public FileStatus[] CheckSumFileSystem#listStatus(Path p, final PathFilter
filter) throws IOException {
fs.listStatus(p, new PathFilter() {
public boolean accept(Path file) {
return (!isChecksumFile(file) && filter.accept(file));
}
};
}
{noformat}
i.e., composing the filters.
> Path filter for Local file system list .crc files

> If we write a path filter for local file system, it lists .crc files also.
> If dont pass any filter, it lists paths properly without any .crc files. But
> we write a filter, it does list .crc files also.
