-----------------------------------
Summary: Propose to expose Metrics Sink and Source interface
Key: SPARK-14151
URL: https://issues.apache.org/jira/browse/SPARK-14151
Project: Spark
Issue Type: Improvement
Components: Spark Core
Reporter: Saisai Shao
Priority: Minor
MetricsSystem is designed for plug-in different sources and sinks, user could
write their own sources and sinks and configured through metrics.properties,
MetricsSystem will register it through reflection. But current Source and Sink
interface is private, which means user cannot create their own sources and
sinks unless using the same package.
So here propose to expose source and sink interface, this will let user build
and maintain their own source and sink, alleviate the maintenance overhead of
spark codebase.
