SPARK2与Phoenix整合的方法是什么

1、环境说明

2、条件

1. HBase 安装完成

2. Phoenix 已经启用，Ambari界面如下所示：

3. Spark 2安装完成

3、Spark2 与 Phoenix整合

步骤：

1. 进入 Ambari Spark2 配置界面

2. 找到自定义 spark2-defaults并添加如下配置项：

   spark.driver.extraClassPath=/usr/hdp/current/phoenix-client/phoenix-4.10.0-HBase-1.2-client.jar
   spark.executor.extraClassPath=/usr/hdp/current/phoenix-client/phoenix-4.10.0-HBase-1.2-client.jar
   

4、Yarn HA 问题

如果配置了Yarn HA, 则需要修改 Yarn HA 配置，否则spark-submit提交任务会报如下错误：

Exception in thread "main" java.lang.IllegalAccessError: tried to access method org.apache.hadoop.yarn.client.ConfiguredRMFailoverProxyProvider.getProxyInternal()Ljava/lang/Object; from class org.apache.hadoop.yarn.client.RequestHedgingRMFailoverProxyProvider

修改Yarn HA配置：

将原来的配置:

yarn.client.failover-proxy-provider=org.apache.hadoop.yarn.client.RequestHedgingRMFailoverProxyProvider

改为现在的配置：

yarn.client.failover-proxy-provider=org.apache.hadoop.yarn.client.ConfiguredRMFailoverProxyProvider

如果没有配置 Yarn HA, 则不需要进行此步配置
