[Hadoop-common-dev] [jira] Created: (HADOOP-4080) name node should provide status of dfs.name.dir's

name node should provide status of dfs.name.dir's
-------------------------------------------------

Key: HADOOP-4080
URL: https://issues.apache.org/jira/browse/HADOOP-4080
Project: Hadoop Core
Issue Type: New Feature
Components: dfs
Affects Versions: 0.18.0
Reporter: Allen Wittenauer
Fix For: 0.19.0


We've had several reports of people letting their dfs.name.dir fill up. To help prevent this, the name node web ui and perhaps dfsadmin -report or another command should give a disk space report of all dfs.name.dir's as well as whether or not the contents of that dir are actually being used, if the copy is "good", last 2ndary name node update, and any thing else that might be useful.
