Subject determining which region a mapper processed
Date Sun, 20 Jul 2014 15:52:39 GMT
When  a MapReduce job is run against HBase, a mapper is created for each region (using TableInputFormat).
Is there a way look at the history and determine which region a given mapper ran against?
Or can I rely on 
the mapper number being the same as the region number?
