Description

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.
