             Summary: Two Shell 'close_region' Example Syntaxes Don't Work
                 Key: HBASE-15799
                 URL: https://issues.apache.org/jira/browse/HBASE-15799
             Project: HBase
          Issue Type: Bug
          Components: shell
    Affects Versions: 2.0.0
            Reporter: Matt Warhaftig
            Assignee: Matt Warhaftig
            Priority: Minor


The close_region shell command's help message lists the following usage syntaxes:

{noformat}
hbase> close_region 'REGIONNAME'
hbase> close_region 'REGIONNAME', 'SERVER_NAME'
hbase> close_region 'ENCODED_REGIONNAME'
hbase> close_region 'ENCODED_REGIONNAME', 'SERVER_NAME'
{noformat}

admin.rb's current code (with close_region method being the entry point) is:
{code}
def close_region(region_name, server)
  if (server == nil || !closeEncodedRegion?(region_name, server))
    @admin.closeRegion(region_name, server)
  end
end

def closeEncodedRegion?(region_name, server)
   @admin.closeRegionWithEncodedRegionName(region_name, server)
end
{code}

The {{close_region 'ENCODED_REGIONNAME'}} syntax currently will not work because when server = nil the {{closeEncodedRegion}} method call is skipped.

The {{close_region 'REGIONNAME', 'SERVER_NAME'}} syntax currently will not work because {{@admin.closeRegionWithEncodedRegionName}} throws an NotServingRegionException (for the non-encoded region_name) that is uncaught in and prevents execution from returning to {{close_region}} and the correct call of {{HBaseAdmin.closeRegion}}.
