stack commented on HBASE-7201:
------------------------------
Redid the attached patch as a removal of HbaseMapWritable over in HBASE-7232.
Would like to get that in as subtask on this issue.
I looked at what else is involved converting HFile. There is an awkward meta
block functionality that takes 'Writable' which is a little exotic but is used
by the bloom filter stuff. Its awkward. I could convert to Message but not
sure how to make it backward compatible just yet.

> Some of the remaining discussions for PB conversions:
> - Convert the HFile/HLog metadata to PB.
> - WALEdit, HLogKey should be converted? We don't want to repeat the PBMagic,
> and the PB overhead can be high, but this is needed for replication?
> - We said no to converting KV.
> These should not block 0.96.
