Description

See other issues with decommissioning: ACCUMULO-4004

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.
