Keith Turner updated ACCUMULO-418:
----------------------------------
Fix Version/s: (was: 1.4.1)
(was: 1.3.6)
Assignee: Keith Turner (was: Eric Newton)
I suspect this will require modifications to the file format to make it more of
a local operation. With the current file format, the index (at the end of the
file and possibly in a remote block) must be read.
> Make RFiles splittable

> 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
> is no easy way to do this currently as there is no RFile RecordReader or
> InputFormat provided.
