> When an empty namenode storage directory is detected on normal NN startup, it 
> may not be fully initialized. The new directory is still part of "in-service" 
> NNStrage and when a checkpoint image is uploaded, a copy will also be written 
> there.  However, the retention manager won't be able to purge old files since 
> it is lacking a VERSION file.  This causes fsimages to pile up in the 
> directory.  With a big name space, the disk will be filled in the order of 
> days or weeks.
