> The region_mover loadRegion function incorrectly uses 'isSuccessfulScan':
> {noformat} 
>   for r in regions
>     exists = false
>     begin
>       exists = isSuccessfulScan(admin, r)
>     rescue org.apache.hadoop.hbase.NotServingRegionException => e
>       $LOG.info("Failed scan of " + e.message)
>     end
> {noformat} 
> isSuccessfulScan throws an exception when it fails rather than returning status.
> As a result empty regions don't get restored - this is the case in a fresh install (which
is how I discovered this) with no user table.
> Modifying the code to set exists IF isSuccessfulScan does not throw an exception worked
for me:
> {noformat}
>   for r in regions
>     exists = false
>     begin
>       isSuccessfulScan(admin, r)
>       exists = true
>     rescue org.apache.hadoop.hbase.NotServingRegionException => e
>       $LOG.info("Failed scan of " + e.message)
>     end
> {noformat}
