Subject [jira] [Commented] (HBASE-6439) Ignore .archive directory as a table
Date Thu, 27 Sep 2012 19:17:08 GMT

--------------------------------------------

Here's the review:

https://reviews.apache.org/r/7225/

[~jesse_yates] [~saint.ack@gmail.com] - Say what ? I am misunderstanding this bug then. I
figured that there are log lines because some directories are not deletable. Also that it
was to be made configurable from what was a constant. Aren't some archive dirs created under
region dirs: as in HFileArchiveUtil >> getStoreArchivePath method ? and therefore not
a constant ?

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.
