Serialize NN edits log as avro records
--------------------------------------
Key: HDFS-842
URL: https://issues.apache.org/jira/browse/HDFS-842
Project: Hadoop HDFS
Issue Type: New Feature
Components: name-node
Reporter: Todd Lipcon
Right now, the edits log is a mishmash of ad-hoc serialization and Writables.
Switching it over to Avro records would be really useful for operator tools -
an "offline edits viewer" would become trivial ("avrocat")
