Or move line-reading code to util?

> Should we get this from the FileSystem cache?
It should use FileSystem#statisticsTable (which, incidentally, should be named
STATISTICS_TABLE).
Perhaps we should add a FileSystem method like:
public static Map<String, Statistics> getStatistics();
That returns the stats indexed by URI scheme?
> Fix and enforce module dependencies

> Since HADOOP-2916 Hadoop Core consists of modules in independent source
> trees: core, hdfs, mapred (and others). The dependencies between them should
> be enforced to avoid cyclic dependencies. At present they all have
> dependencies on each other.
