I tried to use TableMapper and TableOutputFormat in from org.apache.hadoop.hbase.mapreduce to write a map-reduce which incremented some columns. I noticed that TableOutputFormat.write() doesn't support Increment, only Put and Delete.
Is there a reason that TableOutputFormat shouldn't support increment? I think adding support for increment would only require adding a copy constructor to Increment and a few lines to TableOutputFormat: I'd be willing to give writing the patch a try if there's no objection. Leif Wickland
