Currently this routine is > called by addToReplicasMap() for every blockfile in the directory tree, and > it walks each file's containing directory on every call. There is a simple > refactoring that should make it more efficient. > This work item is one of four sub-tasks for HDFS-1443, Improve Datanode > startup time. > The fix will probably be folded into sibling task HDFS-1446, which is already > refactoring the method that calls getGenerationStampFromFile(). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
