Subject [jira] [Commented] (HBASE-6818) [WINDOWS] Catalog table .META. violates the naming convention in Window OS
Date Tue, 18 Sep 2012 23:20:08 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6818?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13458273#comment-13458273

Enis Soztutar commented on HBASE-6818:

This is a hard one to tackle, since the META table's name is all over the code base. It is
not straight, or even sensible, to change the name of the META table. Instead, we can work
on a solution that changes the file name of the META table at the file system level, if the
underlying filesystem is local (and windows). we also have to standardize on the local file
name of the META table, so that we dont allow user level tables of that name.

> 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.
