--------------------------------------
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}}.
