Jim Kellerman commented on HADOOP-1519:
---------------------------------------

I am wondering why you needed to create the RecordWritable class. Couldn't you 
use ArrayWritable(KeyedData.class) ?

Also, in the future, it would be most beneficial if you could create a patch 
instead of sending all the files. If you use eclipse, it is as simple as right 
click on the project -> Team -> Create Patch...

Since you sent all the sources, I had to diff all the HBase files to find out 
that all you had changed was HClient and that change was only the addition of 
the method getStartKeys.

> mapreduce input and output formats to go against hbase
