Enis Soztutar updated HBASE-6818:
---------------------------------
Attachment: hbase-6818-newapproach-0.94_v1.patch
Continuing on windows support, attaching a patch for this .META. naming issue
under windows.
Instead of handing the META table name, I opted for another approach, where we
only special-case where we get the table name from underlying file system. NTFS
converts the path <hbase.root.dir>/.META. to <hbase.root.dir>/.META but sub
paths still work (we can still refer <hbase.root.dir>/.META./regionname which
will be converted by NTFS). So, we just need to handle conversion where we do
ls, and see .META, which is then treated as .META.
The patch is not for inclusion right now since it targets 0.94. Namespace issue
(HBASE-8015) will already change the META table's name, so we won't need this
at all. Will close this one, once we have namespaces (hopefully soon :))

> There are two catalog tables in HBase, ROOT and .META., whose representitives
> in Windows file system are folders. However, the name of .META. table
> violates the naming convention in Windows, as Windows doesn't support any
> file/directory whose name ending with a period '.'.
> The following are the related description from msdn.microsoft.com for naming
> convention for Windows :
> Do not end a file or directory name with a space or a period. Although the
> underlying file system may support such names, the Windows shell and user
> interface does not. However, it is acceptable to specify a period as the
> first character of a name. For example, ".temp".
> Note that this does not affect hdfs, but only RawLocalFileSystem, and
> single-node local hbase clusters.
