> In IMPALA-6857 we added a thread that checks for GC pauses a bit. To allow monitoring tools to pick up on the fact that pauses are happening, it's useful to promote those as full-fledged metrics.
> It turns out we were also collecting those metrics by doing a lot of round trips to the Java side of the house. This JIRA may choose to address that as well.
