> This patch reduces Hadoop's dependency on an old version of guava. Stopwatch.elapsedMillis()
isn't part of guava past v16 and the tools I'm working on use v17. 
> To remedy this and also reduce Hadoop's reliance on old versions of guava, we can use
the Apache StopWatch (org.apache.commons.lang.time.StopWatch) which provides nearly equivalent
functionality. apache.commons.lang is already a dependency for Hadoop so this will not introduce
new dependencies.
