> Odd is that the file thats missing's name is not cited.
> The other instance showed in the webui. Seemed to be problem with an
> HStoreFile in.META. region. I was unable to select content from the .META.
> table -- it was returning null rows.
> In both cases a restart fixed things again.
> Since all state is out in hdfs and the in-memory maps are made from the hdfs
> state, something must not be getting updated on compaction/split or flush.
