Jesse Yates updated HBASE-6439:
-------------------------------

    Attachment: hbase-6439-r0.patch

Talked with Sameer and am picking up work on this ticket. Attaching patch that removes the configurability of the the archive directory for a hardcoded archive directory. Also updating the uses where the archive directory is looked up and/or referenced in comments (HFileLink). Also added a test to FSDescriptors for ensuring the right response to looking up the archive directory.

> 2012-07-22 02:27:30,699 WARN  [IPC Server handler 0 on 47087] util.FSTableDescriptors(168): The following folder is in HBase's root directory and doesn't contain a table descriptor, do consider deleting it: .archive
> {quote}
> With the addition of HBASE-5547, table-level folders are no-longer all table folders. FSTableDescriptors needs to then have a 'gold-list' that we can update with directories that aren't tables so we don't have this kind of thing showing up in the logs.
> Currently, we have the following block:
> {quote}
>     invocations++;
>     if (HTableDescriptor.ROOT_TABLEDESC.getNameAsString().equals(tablename)) {
>       cachehits++;
>       return HTableDescriptor.ROOT_TABLEDESC;
>     }
>     if (HTableDescriptor.META_TABLEDESC.getNameAsString().equals(tablename)) {
>       cachehits++;
>       return HTableDescriptor.META_TABLEDESC;
>     }
> {quote}
> to handle special cases, but that's a bit clunky and not clean in terms of table-level directories that need to be ignored.
