Subject [jira] [Created] (ACCUMULO-1524) Abstract file pointers in metadata table
Date Wed, 19 Jun 2013 21:02:20 GMT
Christopher Tubbs created ACCUMULO-1524:
-------------------------------------------

             Summary: Abstract file pointers in metadata table
                 Key: ACCUMULO-1524
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1524
             Project: Accumulo
          Issue Type: Improvement
            Reporter: Christopher Tubbs


ACCUMULO-118 interprets full URIs for file entries. It may be useful to instead to store a
VolumeID + path, with a separate VolumeID -> URI mapping in configuration, for a level
of indirection. This helps keep the METADATA from needing to be rewritten in strange cases,
like moving a namenode from one host to another, or DNS name/IP address of namenode changes,
or switching to a redundant fail-over DFS instance.
