Subject [jira] [Commented] (ACCUMULO-1773) Garbage collector may delete referenced files after upgrade
Date Fri, 11 Oct 2013 16:22:42 GMT


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
