Review comment:
       I think a better approach might be to not create one metrics updater per 
task, and create a single updater instead, which iterates over all the tasks 
and updates records/bytes written.

Review comment:
       Using the global "metrics.enabled" key to turn off task metrics 
reporting seems too heavy. This global config will turn off other reporting as 
well, e.g. GTEs, and other metrics.
