Hairong Kuang updated HDFS-204:
---

Attachment: getFileNum-yahoo20.patch

This patch ported the feature to Yahoo 20 branch. In addition, it fixed the bug 
that NPE will be thrown when getListing on a non-existent path and I also added 
two more test cases, one is listing a non-existent path and one is listing path 
represented a file.

 Key: HDFS-204
 URL: https://issues.apache.org/jira/browse/HDFS-204
 Project: Hadoop HDFS
  Issue Type: New Feature
  Components: name-node
Affects Versions: 0.21.0
Reporter: Koji Noguchi
Assignee: Jitendra Nath Pandey
 Fix For: 0.21.0

 When namenode becomes unresponsive by HADOOP-4693 (large filelist calls), 
 metrics has been helpful in finding out the cause.
 When gc time hikes, FileListed metrics also hiked.
 In 0.18, after we *fixed* FileListed metrics so that it shows number of 
 operations instead of number of files listed (HADOOP-3683), I stopped seeing 
 this relationship graph.  
 Can we bring back NumbverOfFilesListed metrics?
