> Over in HBASE-11591 there was a need to set the sequenceId of the HFile to the bulk loaded
KVs.  Since we are trying to use the concept of Cells in the read path if we need to use setSequenceId(),
then the Cell has to be converted to KV and only KeyValue impl has the accessor setSequenceId().
> [~anoop.hbase] suggested if we can use a Server side impl of Cell and have these accessors
in them.
> This JIRA aims to solve this and see the related code changes that needs to be carried
out for this.
