[jira] Created: (HDFS-842) Serialize NN edits log as avro records

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")
