Over on the Nutch dev list there's been a bit of chatter about
files/folders generated by Hadoop (generally speaking 0.17) such as
'_logs'. Digging through Hadoop a bit revealed that there is a
private hiddenFileFilter in FileInputFilter.java. This is similar to
what I came up with here:
I couldn't find any other mention of "hidden" files in the Hadoop
codebase or the wiki and little on the mailing lists.
Is there a defined standard for hidden files or a public interface for
determining file visibility?
