> In follow-up discussion to HBASE-11620, Enis brought up this point:
> Related to this, should not we also write the CellCodec that we use in the
> WAL header. Right now, the codec comes from the configuration which means
> that you cannot read back the WAL files if you change the codec.
> This JIRA is to implement the above suggestion.
