---------------------------------------------

Only one unit test failure with this patch. TestMapReduceLocal fails as in HADOOP-4907.

> Trash opens FileSystem using Path.getFileSystem() but never closes it.
> This happens even if Trash is disabled (trash.interval == 0). 
> I think trash should not open file system if it is disabled.
> I also think that NameNode should not create a trash Thread when trash is disabled, see NameNode.init().
