Eric Liang 23c58653f9 [SPARK-16238] Metrics for generated method and class bytecode size ... ## What changes were proposed in this pull request? This extends SPARK-15860 to include metrics for the actual bytecode size of janino-generated methods. They can be accessed in the same way as any other codahale metric, e.g. ``` scala> org.apache.spark.metrics.source.CodegenMetrics.METRIC_GENERATED_CLASS_BYTECODE_SIZE.getSnapshot().getValues() res7: Array[Long] = Array(532, 532, 532, 542, 1479, 2670, 3585, 3585) scala> org.apache.spark.metrics.source.CodegenMetrics.METRIC_GENERATED_METHOD_BYTECODE_SIZE.getSnapshot().getValues() res8: Array[Long] = Array(5, 5, 5, 5, 10, 10, 10, 10, 15, 15, 15, 38, 63, 79, 88, 94, 94, 94, 132, 132, 165, 165, 220, 220) ``` ## How was this patch tested? Small unit test, also verified manually that the performance impact is minimal (<10%). hvanhovell Author: Eric Liang <ekl@databricks.com> Closes #13934 from ericl/spark-16238.		2016-06-29 15:07:32 -07:00
