Project: Hadoop HDFS
Issue Type: Improvement
Components: name-node
Affects Versions: 0.23.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Trivial
Fix For: 0.23.0
This is simple cleanup in FSEditLogLoader - rather than having a variable per
operation type, we can just use an EnumMap to count how many instances of each
opcode we've hit.
