[~dlmarion] found HDFS-8208, which might be causing the problem.

> While decommissioning several racks, accumulo experienced an error closing the result
of a compaction.  In particular, the error was due to insufficiently replicated blocks, and
those blocks were on the decommissioned racks.  However, the resulting files (with the extension
".rf_tmp" are not deleted.  These abandoned files prevent the datanodes from finishing their
decommissioning.
