Reduce the number of calls of HarFileSystem.getFileStatus in RaidNode
---------------------------------------------------------------------
Key: MAPREDUCE-1823
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1823
Project: Hadoop Map/Reduce
Issue Type: Improvement
Affects Versions: 0.22.0
Reporter: Scott Chen
Assignee: Scott Chen
Fix For: 0.22.0
RaidNode makes lots of calls of HarFileSystem.getFileStatus. This method
fetches information from DataNode so it is slow. It becomes the bottleneck of
the RaidNode. It will be nice if we can make this more efficient.
