Subject Custom Spark metrics?
Date Tue, 16 Jun 2015 23:13:47 GMT
I'm looking at the doc here:

Is there a way to define custom metrics in Spark, via Coda Hale perhaps, and
emit those?

Can a custom metrics sink be defined?

And, can such a sink collect some metrics, execute some metrics handling
logic, then invoke a callback and notify the Spark consumers that had
emitted the metrics that that logic has been executed?
