Run HiveFromSpark example with MASTER=yarn-cluster

Question

I'm trying to run HiveFromSpark example on my EMR Spark/Hive cluster.

The Problem

Using yarn-client : 

~/spark/bin/spark-submit --master yarn-client --num-executors=19 --class org.apache.spark.examples.sql.hive.HiveFromSpark  ~/spark/lib/spark-examples-1.3.0-hadoop2.4.0.jar

works like a charm. But, using yarn-cluster : 

~/spark/bin/spark-submit --master yarn-cluster --num-executors=19 --class org.apache.spark.examples.sql.hive.HiveFromSpark ~/spark/lib/spark-examples-1.3.0-hadoop2.4.0.jar

fails with: 

Exception in thread "main" org.apache.spark.SparkException: Application finished with failed status
    at org.apache.spark.deploy.yarn.Client.run(Client.scala:622)
    at org.apache.spark.deploy.yarn.Client$.main(Client.scala:647)

    at org.apache.spark.deploy.SparkSubmit$.main(SparkSubmit.scala:110)
    at org.apache.spark.deploy.SparkSubmit.main(SparkSubmit.scala)

and the error message in Resource Manager says: 

User class threw exception: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient

提交时使用--jars选项添加datanucleus jar，并将hive-site.xml添加到驱动程序类路径，以便spark可以读取hive配置。 

--jars spark/lib_managed/jars/datanucleus-api-jdo-3.2.6.jar,spark/lib_managed/jars/datanucleus-rdbms-3.2.9.jar,spark/lib_managed/jars/datanucleus-core-3.2.10.jar,spark/mysql-connector-java-5.0.8-bin.jar --files hive/conf/hive-site.xml

For me hadooped's answer actually failed with an error of: 

15/06/02 17:41:41 ERROR Datastore.Schema: Failed initialising database. Unable to open a test connection to the given database. JDBC url = jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true, username = hive. Terminating connection pool (set lazyInit to true if you expect to start your database after your app). Original Exception:
------ java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true

But it worked when I removed the hive-site.xml file argument and used the proper paths (for EMR as of 2015-6-1): 

--jars spark/lib/datanucleus-api-jdo-3.2.6.jar,spark/lib/datanucleus-core-3.2.10.jar,spark/lib/datanucleus-rdbms-3.2.9.jar,hive/lib/mysql-connector-java-5.1.30.jar

I faced the same issue while executing Spark Hive code.

Spark version 2.0.2

Hive version 1.2.1

The issue got fixed when I added following jars and hive-site.xml to the classpath:

/usr/hdp/2.5.3.0-37/spark2/jars/datanucleus-api-jdo-3.2.6.jar,   
/usr/hdp/2.5.3.0-37/spark2/jars/datanucleus-core-3.2.10.jar,   
/usr/hdp/2.5.3.0-37/spark2/jars/datanucleus-rdbms-3.2.9.jar
