Akira AJISAKA commented on HADOOP-9087:
---------------------------------------

The test failure is not related to the patch. I couldn't reproduce the error locally.

> Came across this while looking at the code for the metrics system: the qsize gauge in
the MetricsSinkAdapter is not updated/maintained so it will always be zero (there's a compiler
warning about it actually).
