Keith Turner commented on ACCUMULO-1773:
----------------------------------------
Discussed this with [~ecn] and [~ctubbsii] and we decided to only use the
suffix /<accumulo dir>/tables/<table id>/<tablet dir>/<file> for determining if
a file is referenced. Since file names are unique this should not lead to
false negatives (decide not to delete something that should be deleted). But
even if it did, a bug w/ false negatives would be preferable to false
positives.

> Looking at the srouce code, it seems like the garbage collector uses a
> mixture of relative and absolute paths when determining what files to delete.
> I think if a deletion candidate is an absolute path and the reference is a
> relative path then it could delete the referenced file.
