> 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.
