Request for Hadoop metrics and making emitRecords public

[Jason Venner <ja...@attributor.com>]

We have operations that need to force the metric records out at a 
specific point in time. We want to emit the complete task counter 
records after JobClient.runJob, and the jvm has a limited life after 
that point, and our metrics records are not being emitted.

Currently the emitRecords call is only made from within the timeout 
handler, and is private.

What do people thing of opening up the interface to allow applications 
to force an output.

I originally would have added a flush method, but the way that is used 
is not relevant to this problem. flush expects emitRecords to have been 
called and flushes the emitted data to the destination.
