1、环境说明
| 操作系统 | CentOS Linux release 7.4.1708 (Core) |
|---|---|
| Ambari | 2.6.x |
| HDP | 2.6.3.0 |
| Spark | 2.x |
| Phoenix | 4.10.0-HBase-1.2 |
2、条件
HBase 安装完成
-
Phoenix 已经启用，Ambari界面如下所示：
Spark 2安装完成
3、Spark2 与 Phoenix整合
Phoenix 官网整合教程： http://phoenix.apache.org/phoenix_spark.html
步骤：
-
进入 Ambari Spark2 配置界面
-
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.jarmark
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
