Description

Sometimes it is helpful to get the region location given a specified key, without having to scan meta and look at the keys.

so, having in the shell something like:

hbase(main):008:0> locate_region 'testtb', 'z'
HOST                         REGION                                                                           
 localhost:42006             {ENCODED => 7486fee0129f0e3a3e671fec4a4255d5, 
                              NAME => 'testtb,m,1449508841130.7486fee0129f0e3a3e671fec4a4255d5.',
                              STARTKEY => 'm', ENDKEY => ''}
