region_mover.rb fails to load -ROOT- region back to original server in deployment with no user
tables.
------------------------------------------------------------------------------------------------------

                 Key: HBASE-5502
                 URL: https://issues.apache.org/jira/browse/HBASE-5502
             Project: HBase
          Issue Type: Bug
          Components: scripts
    Affects Versions: 0.92.0
         Environment: Ubuntu precise
            Reporter: James Page
            Priority: Minor


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}
