Chris Douglas updated HADOOP-4758:
----------------------------------
Attachment: 4758-0.patch
The attached patch modifies the utility and factory to separate the context
name defining the metric class and the context name for its properties. It also
adds a composite context to split output between its subcontexts.
Note that this doesn't support splitting metrics between two contexts with
intersecting properties.
> Add a 'tee' for metrics contexts
