使用MASTER = yarn-cluster运行HiveFromSpark示例

标签： hadoop apache-spark amazon-emr apache-spark-sql

我试图在我的EMR Spark / Hive群集上运行HiveFromSpark示例。

问题

使用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

就像一个魅力。但是，使用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

失败了：

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)

并且资源管理器中的错误消息显示：

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

群集设置

EMR配置

我使用Install Spark（s3：//support.elasticmapreduce/spark/install-spark）引导操作和Setup Hive步骤设置群集。

3 个答案:

答案 0 :(得分：5)

在提交时使用--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可以读取配置单元配置。

--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

答案 1 :(得分：0)

对于我来说，hadooped的回答实际上失败了，错误是：

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

但是当我删除了hive-site.xml文件参数并使用了正确的路径（对于2015-6-1中的EMR）时，它有效：

--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

答案 2 :(得分：0)

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
