stack commented on HBASE-13450:
-------------------------------
bq. It is upto us pass a byte[] to it. I think it is better this way, right?
Why write anything if comparator is null?
bq. What can we do there?
Deprecate the old and add new method (change the order of the params so you can
do override or come up with new method name).
> Purge RawBytescomparator from the writers and readers after HBASE-10800

> Currently KeyValue.RAW_COMPARATOR is written in the Trailer of the HFiles.
> Ideally this need not be persisted to the trailer of the Hfiles because only
> the ROW bloom and the meta index blocks uses this. Currently RAW_COMPARATOR
> is also of type KVComparator.
> HBASE-10800 would introduce CellComparator and would expect only cells to be
> compared. We cannot have RAW_COMPARATOR a type of CellComparator. Hence it
> is better to avoid writing the RAW_COMPARATOR to the FFT and whereever we
> need RAW_COMPARATOR we will directly use it as Bytes.BYTES_RAWCOMPARATOR.
