Description
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.
