Steve Loughran commented on HADOOP-5958:
----------------------------------------
@Aaron, out of curiosity, what happens when you run that same benchmark against
an NFS drive? I am worried that the caching is going to be useful for anyone
serving up content from a remote FS, even through the Java APIs
> Use JDK 1.6 File APIs in DF.java wherever possible

> JDK 1.6 has File APIs like File.getFreeSpace() which should be used instead
> of spawning a command process for getting the various disk/partition related
> attributes. This would avoid spikes in memory consumption by tasks when
> things like LocalDirAllocator is used for creating paths on the filesystem.
