[jira] [Commented] (ACCUMULO-4008) accumulo compactions prevent datanode decommission

Eric Newton commented on ACCUMULO-4008:
---------------------------------------

Open WAL's prevent the datanodes from shutting down. If there's enough live ingest, the files will roll naturally, but in this case, most data was loaded by bulk import.

> 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.
