public class Classification
extends software.amazon.jsii.JsiiObject

The classification within a EMR Containers application configuration.

Class can be extended to add other classifications. For example, new Classification('xxx-yyy');

Example:

 EmrContainersStartJobRun.Builder.create(this, "EMR Containers Start Job Run")
         .virtualCluster(VirtualClusterInput.fromVirtualClusterId("de92jdei2910fwedz"))
         .releaseLabel(ReleaseLabel.EMR_6_2_0)
         .jobName("EMR-Containers-Job")
         .jobDriver(JobDriver.builder()
                 .sparkSubmitJobDriver(SparkSubmitJobDriver.builder()
                         .entryPoint(TaskInput.fromText("local:///usr/lib/spark/examples/src/main/python/pi.py"))
                         .build())
                 .build())
         .applicationConfig(List.of(ApplicationConfiguration.builder()
                 .classification(Classification.SPARK_DEFAULTS)

                         "spark.executor.instances", "1",
                         "spark.executor.memory", "512M"))
                 .build()))
