Keith Turner commented on ACCUMULO-418:
---------------------------------------
Would you like to see this in 1.4.x? If so, then we could possibly create a
reader that uses the current file format and reads the index at the end of the
file. For 1.5 we can change the file format to avoid reading the index.

> There are times when iterating over RFiles is useful in map-reduce jobs. I
> know that RFiles logically can be split on the block boundary, however there

> InputFormat provided.
