[Hadoop Wiki] Update of "Hbase/MapReduce" by JimKellerman

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The following page has been changed by JimKellerman:

------------------------------------------------------------------------------
  
  Running mapreduce jobs that have hbase as source or sink, you'll need to specify source/sink table and column names in your configuration.
  
- Reading from hbase, the TableInputFormat asks hbase for the list of regions and makes a map-per-region.  Writing, its better to have lots of reducers so load is spread across the hbase cluster.
