Ajith c324e1da9d [SPARK-27122][CORE] Jetty classes must not be return via getters in org.apache.spark.ui.WebUI ... ## What changes were proposed in this pull request? When we run YarnSchedulerBackendSuite, the class path seems to be made from the classes folder(resource-managers/yarn/target/scala-2.12/classes) instead of jar (resource-managers/yarn/target/spark-yarn_2.12-3.0.0-SNAPSHOT.jar) . ui.getHandlers is in spark-core and its loaded from spark-core.jar which is shaded and hence refers to org.spark_project.jetty.servlet.ServletContextHandler Here in org.apache.spark.scheduler.cluster.YarnSchedulerBackend, as its not shaded, it expects org.eclipse.jetty.servlet.ServletContextHandler Refer discussion https://issues.apache.org/jira/browse/SPARK-27122?focusedCommentId=16792318&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16792318 Hence as a fix, org.apache.spark.ui.WebUI must only return a wrapper class instance or references so that Jetty classes can be avoided in getters which are accessed outside spark-core ## How was this patch tested? Existing UT can pass Closes #24088 from ajithme/shadebug. Authored-by: Ajith <ajith2489@gmail.com> Signed-off-by: Sean Owen <sean.owen@databricks.com>		2019-03-17 06:44:02 -05:00
