Description

Saw a complaint about a missing file in a major compaction.

The file was recently created by a flush.

After looking around, I found the file was deleted when the directory containing the file was deleted by the gc. The gc is not supposed to delete directories that have entries in the METADATA table. From the loading of the tablet, I can definitely see the directory entry.

Create a unit test for this case against MockAccumulo to verify the problem.
