Need to tweak a few things in the metrics package to support the Simon plugin
-----------------------------------------------------------------------------
Key: HADOOP-204
URL: http://issues.apache.org/jira/browse/HADOOP-204
Project: Hadoop
Type: Improvement
Components: metrics
Reporter: David Bowen
Assigned to: David Bowen
(1) added an extra metrics.jar target to the build.xml so that I can build a
stand-alone library containing only the
metrics package and its subpackages.
(2) added serialversionUIDs to a bunch of classes to make Eclipse happy
(3) made AbstractMetricsContext.createRecord final, and added a protected
newRecord that subclasses can use
to customize record creation without breaking the parent class.
(4) minor fix to how errors in callbacks are handled
(5) constructor in MetricsRecordImpl made protected rather than package private
so that it can be subclassed
(6) extended Util.parse(String serverSpecs, int defaultPort) to handle the case
of a null serverSpecs by defaulting to localhost
