> RegionServer was carrying -ROOT- and having trouble writing HDFS.
> RegionServer judged that a flush failed and reported a
> DroppedSnapshotException. Usually, the filesystem check would fail and set
> all the abort flags but it in this case filesystem somehow returned healthy
> and the flags were not set. The code path shutdown the RPC only and exited
> then we exited the Flusher. All the rest of the RegionServer stayed up and
> kept reporting the master. The master thought it alive and kept trying to
> scan the unreachable -ROOT-. Cluster was hosed until manual intervention 20
> minutes later.
