> There was some advocacy of using Avro for serialization of HBase WAL records up on hbase-dev@.
Idea is Hadoop core is getting away from Writables and Avro is the blessed replacement. 
> I think we have this criteria for its use:
> 1) Performance of writing Avro records is no worse than that for writing Writables into
a SequenceFile.
> 2) Space consumed by Avro serialization is no worse than that of Writables
> 3) File format is amenable to appends (cannot require valid trailers, etc.)
> I'll put up a patch so we can try it out.
