Subject [jira] [Commented] (HBASE-13451) Make the HFileBlockIndex blockKeys to Cells so that it could be easy to use in the CellComparators

------------------------------------------------

bq.Which blockKeys are written with RawBytesComparator?
Meta block keys.  They are just raw bytes. Hence we use RAW_COMPARATOR while reading back.

> After HBASE-10800 we could ensure that all the blockKeys in the BlockReader are converted
to Cells (KeyOnlyKeyValue) so that we could use CellComparators. Note that this can be done
only for the keys that are written using CellComparators and not for the ones using RawBytesComparator.
