Ambari HDP 下 SPARK2 与 Phoenix 整合
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.jarspark.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 at org.apache.hadoop.yarn.client.RequestHedgingRMFailoverProxyProvider.init(RequestHedgingRMFailoverProxyProvider.java:75) at org.apache.hadoop.yarn.client.RMProxy.createRMFailoverProxyProvider(RMProxy.java:163) at org.apache.hadoop.yarn.client.RMProxy.createRMProxy(RMProxy.java:94) at org.apache.hadoop.yarn.client.ClientRMProxy.createRMProxy(ClientRMProxy.java:72) at org.apache.hadoop.yarn.client.api.impl.YarnClientImpl.serviceStart(YarnClientImpl.java:187) at org.apache.hadoop.service.AbstractService.start(AbstractService.java:193) at org.apache.spark.deploy.yarn.Client.submitApplication(Client.scala:153) at org.apache.spark.scheduler.cluster.YarnClientSchedulerBackend.start(YarnClientSchedulerBackend.scala:56) at org.apache.spark.scheduler.TaskSchedulerImpl.start(TaskSchedulerImpl.scala:173) at org.apache.spark.SparkContext.<init>(SparkContext.scala:509) at org.apache.spark.SparkContext$.getOrCreate(SparkContext.scala:2516) at org.apache.spark.sql.SparkSession$Builder$$anonfun$7.apply(SparkSession.scala:922) at org.apache.spark.sql.SparkSession$Builder$$anonfun$7.apply(SparkSession.scala:914) at scala.Option.getOrElse(Option.scala:121) at org.apache.spark.sql.SparkSession$Builder.getOrCreate(SparkSession.scala:914) at cn.spark.sxt.SparkOnPhoenix$.main(SparkOnPhoenix.scala:13) at cn.spark.sxt.SparkOnPhoenix.main(SparkOnPhoenix.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.i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
