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

             Summary: Change the .META. table name for file system incompatibility
                 Key: HBASE-8093
                 URL: https://issues.apache.org/jira/browse/HBASE-8093
             Project: HBase
          Issue Type: Improvement
          Components: master, Region Assignment, regionserver
    Affects Versions: 0.95.0, 0.98.0
            Reporter: Enis Soztutar
            Assignee: Enis Soztutar
             Fix For: 0.95.0, 0.98.0


Having a table named ".META." causes problems on NTFS file system under windows, since it does not allow file names ending with ".". 

Nicolas and I have been thinking of just changing the name of the META to be {noformat}-META-{noformat}

Since 0.96 is the singularity, and we already moved ROOT to zk, now seems like a good time to do such a change. There will be no rolling upgrade support. 

We can migrate META, and can keep BC, by having an internal alias between the old meta name, and new meta name. This way, outside scripts and code who reads META can still work.
