quota?

[jiang licht <li...@yahoo.com>]

Is it possible to tell hadoop to restrict space usage of a specific dfs folder in the cluster, e.g. a user home directory (/user/accountA in dfs)?

And is there a way to restrict the size of map/reduce output that can be saved to dfs? E.g. if a job creates over-limit data, it won't be allowed to save the result to the dfs.

Thanks,

Michael
