Jean-Daniel Cryans updated HBASE-2471:
--------------------------------------
Attachment: HBASE-2471-v2.patch
Patch that I'm about to commit. It's different from what I posted on RB because
some other unit tests needed to be changed and only figured it out when running
the full test suite.
> Splitting logs, we'll make an output file though the region no longer exists

> The "human unit tester" (Kannan) last night wondered what happens splitting
> logs and we come across an edit whose region has since been removed. Taking
> a look, it looks like we'll create the output file and write the edits for
> the no-longer-extant region anyways. This will leave litter in the
> filesystem -- region split files that will never be used nor removed. This
> issue is about verifying that indeed this is whats happening (We do
> SequenceFile.createWriter with the overwrite flag set to true which tracing
> seems to mean create all intermediary directories -- to be verified) and if
> it indeed is happening, fixing split so unless the region dir exists, don't
> write out edits.. just drop them.
