             Summary: Active walogs deleted when using viewfs
                 Key: ACCUMULO-2080
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2080
             Project: Accumulo
          Issue Type: Sub-task
            Reporter: Keith Turner
            Assignee: Keith Turner
            Priority: Blocker
             Fix For: 1.6.0


While running continuous ingest and agitation using viewfs active walogs were deleted.  

The GC asked the tserver to delete a walogs file.  The tserver checked to see if the file
was in use and determined it was not, when it really was.  The problem was the path from the
GC was normalized and the tserver path was not.   The problem was {{viewfs:/nn1/accumulo/wal/ip-10-1-3-15+9997/bb60f4d4-29a0-4e69-8b0f-dcd44f973cb9}}
was compared to {{viewfs:///nn1/accumulo/wal/ip-10-1-3-15+9997/bb60f4d4-29a0-4e69-8b0f-dcd44f973cb9}}.

The tablet server should be comparing uuids.  This problem could occur w/ filesystems other
than viewfs.
