> 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}}.
