1、環境說明
| 操作系統 | 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、條件
HBase 安裝完成
Phoenix 已經啟用，Ambari界面如下所示：
Spark 2安裝完成
3、Spark2 與 Phoenix整合
Phoenix 官網整合教程： http://phoenix.apache.org/phoenix_spark.html
步驟：
進入 Ambari Spark2 配置界面
找到
自定義 spark2-defaults並添加如下配置項：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 問題
如果配置了Yarn HA, 則需要修改 Yarn HA 配置，否則spark-submit提交任務會報如下錯誤：
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

at java.lang.reflect.Method.i修改Yarn HA配置：
將原來的配置:
yarn.client.failover-proxy-provider=org.apache.hadoop.yarn.client.RequestHedgingRMFailoverProxyProvider
改為現在的配置：
yarn.client.failover-proxy-provider=org.apache.hadoop.yarn.client.ConfiguredRMFailoverProxyProvider
如果沒有配置 Yarn HA, 則不需要進行此步配置
