understanding Rowcounter
Hello,
I have been looking at
http://search-hadoop.com/c/HBase:/src/main/java/org/apache/hadoop/hbase/mapreduce/RowCounter.java%7C%7C+RowCounter
--
the Rowcounter code.
I would like to implement this by using thrift and python without
mapreduce. My guestion is how is the Rowcounter getting the maps for the
mapreduce? I would like to get these maps so I can run it via thrift

You might submit an MR job via thrift, but you don't want to do a rowcount
on a large table without MapReduce.

Region is the split used by mapper.
