Jeffrey Manno resolved ACCUMULO-2535.
-------------------------------------
    Resolution: Duplicate

Closing since PR [https://github.com/apache/accumulo/pull/2175] handles the case where the issue is due to an on-going compaction while trying to be deleted. If that is not the issue then there is not enough information to go off of for an actionable change. A new issue can be created at [https://github.com/apache/accumulo/issues] if this still occurs.

> A large 1.4.4 cluster failed to shutdown cleanly.  It was stuck trying to unload 7 non-root !METADATA tablets.  Master was sending "unload tablet" messages constantly, but the tserver refused to unload the tablets.
> Examining the tserver logs of one server, it began a full major compaction, then received the unload message, and finished the compaction.  The tablet was never unloaded.
> The cluster had ~400 metadata tablets overall.
> System recovered after a hard shutdown of the remaining 8 servers (7 metadata table servers and 1 root tablet server).
