Oleksiy Sayankin commented on SPARK-14358:
------------------------------------------
Hive-2.X.X uses JavaSparkListener
{code}
package org.apache.hadoop.hive.ql.exec.spark.status.impl;
import ...
public class JobMetricsListener extends JavaSparkListener {
{code}
Configuring Hive-2.X.X on Spark-2.0.0 will give an exception:
{code}
2016-09-16T11:20:57,474 INFO [stderr-redir-1]: client.SparkClientImpl
(SparkClientImpl.java:run(593)) - java.lang.NoClassDefFoundError:
org/apache/spark/JavaSparkListener
{code}
Please add JavaSparkListener into Spark-2.0.0
> Change SparkListener from a trait to an abstract class, and remove
> JavaSparkListener

> Reporter: Reynold Xin

> Scala traits are difficult to maintain binary compatibility on, and as a
> result we had to introduce JavaSparkListener. In Spark 2.0 we can change
> SparkListener from a trait to an abstract class and then remove
> JavaSparkListener.
