I'm hoping for a little bit of insight in updating from Hadoop .19.1 to .20.0. I running into quite a bit of deprecated warnings regarding usage of org.apache.hadoop.mapred.*. I understand that the package org.apache.hadoop.mapreduce.* is intended to replace org.apache.hadoop.mapred.* however unless I'm looking at it wrong it seems the majority of the documentation for .20.0, specifically the map reduce tutorial, still uses org.apache.hadoop.mapred.*.
Is it advisable to convert from org.apache.hadoop.mapred.* to org.apache.hadoop.mapreduce.* at this time? If so, are there good examples out there or a basic "how to convert" guide? Thanks
