Ravi Phulari commented on HDFS-218:
-----------------------------------
Is it good idea to show how much disk space is remaining for *dfs.name.dir* in
web ui and in *dfsadmin -report* output ?
How about auto activating Name node Safemode when *dfs.name.dir* remaining
space is below certain percentage? (say 10%)
> name node should provide status of dfs.name.dir's

> 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.
