      Description

      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.
