the value as a byte[] of the String parsed from the command. When performing a read, the column
names outputted are the result of the toString() method of the comparator (the result of which
is not always meaningful), and values are again treated as raw strings. This is almost certainly
broken anywhere that the CF comparator is not UTF8Type and values are anything but strings.
> One possible approach would be to follow HBase's lead and simply allow binary values
to be encoded as strings (see:
