Description

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.
