refactor OEV to share more code with the NameNode
-------------------------------------------------
Key: HDFS-3050
URL: https://issues.apache.org/jira/browse/HDFS-3050
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Colin Patrick McCabe
Assignee: Colin Patrick McCabe
Priority: Minor
Current, OEV (the offline edits viewer) re-implements all of the opcode parsing
logic found in the NameNode. This duplicated code creates a maintenance burden
for us.
OEV should be refactored to simply use the normal EditLog parsing code, rather
than rolling its own.
