本篇文章为大家展示了Spark On MaxCompute如何访问Phonix数据,内容简明扼要并且容易理解,绝对能使你眼前一亮,通过这篇文章的详细介绍希望你能有所收获。
hbase主要版本为2.0与1.1,这边选择对应hbase对应的版本为1.1
Hbase与Hbase2.0版本的区别
HBase1.1版本
1.1版本基于HBase社区1.1.2版本开发。
HBase2.0版本
2.0版本是基于社区2018年发布的HBase2.0.0版本开发的全新版本。同样,在此基础上,做了大量的改进和优化,吸收了众多阿里内部成功经验,比社区HBase版本具有更好的稳定性和性能。
确保测试联通性的可以方便可行,该hbase的VPCId,vsWitchID尽量与购买的独享集成资源组的为一致的。
根据文档链接选择对应的DataWorks的region下的白名单进行添加。
打开数据库链接的按钮,可以查看到Hbase的主版本以及Hbase的专有网络访问地址,以及是否开通公网访问的方式进行连接。
根据hbase的版本为1.1选择Phonix的版本为4.12.0根据文档下载对应的客户端文件ali-phoenix-4.12.0-AliHBase-1.1-0.9.tar.gz
登陆客户端执行命令
./bin/sqlline.py 172.16.0.13,172.16.0.15,172.16.0.12:2181
创建表:
CREATE TABLE IF NOT EXISTS users_phonix ( id INT , username STRING, password STRING ) ;
插入数据:
UPSERT INTO users (id, username, password) VALUES (1, 'admin', 'Letmein');
在客户端执行命令,查看当前表与数据是否上传成功
select * from users;
在IDEA按照对应得Pom文件进行配置本地得开发环境,将代码涉及到得配置信息填写完整,进行编写测试,这里可以先使用Hbase得公网访问链接进行测试,代码逻辑验证成功后可调整配置参数,具体代码如下
package com.git.phonix import org.apache.hadoop.conf.Configuration import org.apache.spark.sql.SparkSession import org.apache.phoenix.spark._ /** * 本实例适用于Phoenix 4.x版本 */ object SparkOnPhoenix4xSparkSession { def main(args: Array[String]): Unit = { //HBase集群的ZK链接地址。 //格式为:xxx-002.hbase.rds.aliyuncs.com,xxx-001.hbase.rds.aliyuncs.com,xxx-003.hbase.rds.aliyuncs.com:2181 val zkAddress = args(0) //Phoenix侧的表名,需要在Phoenix侧提前创建。Phoenix表创建可以参考:https://help.aliyun.com/document_detail/53716.html?spm=a2c4g.11186623.4.2.4e961ff0lRqHUW val phoenixTableName = args(1) //Spark侧的表名。 val ODPSTableName = args(2) val sparkSession = SparkSession .builder() .appName("SparkSQL-on-MaxCompute") .config("spark.sql.broadcastTimeout", 20 * 60) .config("spark.sql.crossJoin.enabled", true) .config("odps.exec.dynamic.partition.mode", "nonstrict") //.config("spark.master", "local[4]") // 需设置spark.master为local[N]才能直接运行,N为并发数 .config("spark.hadoop.odps.project.name", "***") .config("spark.hadoop.odps.access.id", "***") .config("spark.hadoop.odps.access.key", "***") //.config("spark.hadoop.odps.end.point", "http://service.cn.maxcompute.aliyun.com/api") .config("spark.hadoop.odps.end.point", "http://service.cn-beijing.maxcompute.aliyun-inc.com/api") .config("spark.sql.catalogImplementation", "odps") .getOrCreate() //第一种插入方式 var df = sparkSession.read.format("org.apache.phoenix.spark").option("table", phoenixTableName).option("zkUrl",zkAddress).load() df.show() df.write.mode("overwrite").insertInto(ODPSTableName) } }
pom文件中分为Spark依赖,与ali-phoenix-spark相关的依赖,由于涉及到ODPS的jar包,会在集群中引起jar冲突,所以要将ODPS的包排除掉

CREATE TABLE IF NOT EXISTS users_phonix ( id INT , username STRING, password STRING ) ;
在IDEA打包要打成shaded包,将所有的依赖包,打入jar包中,由于DatadWork界面方式上传jar包有50M的限制,因此采用MaxCompute客户端进行jar包
进入DataWorks界面选择左侧资源图标,选择对应的环境位开发换进,输入删除文件时的文件名称进行搜索,列表中展示该资源已经上传成,点击提交到数据开发
点击提交按钮
其中的配置vpcList文件的配置信息如下,可具体根据个人hbase的链接,进行配置
{ "regionId":"cn-beijing", "vpcs":[ { "vpcId":"vpc-2ze7cqx2bqodp9ri1vvvk", "zones":[ { "urls":[ { "domain":"172.16.0.12", "port":2181 }, { "domain":"172.16.0.13", "port":2181 }, { "domain":"172.16.0.15", "port":2181 }, { "domain":"172.16.0.14", "port":2181 }, { "domain":"172.16.0.12", "port":16000 }, { "domain":"172.16.0.13", "port":16000 }, { "domain":"172.16.0.15", "port":16000 }, { "domain":"172.16.0.14", "port":16000 }, { "domain":"172.16.0.12", "port":16020 }, { "domain":"172.16.0.13", "port":16020 }, { "domain":"172.16.0.15", "port":16020 }, { "domain":"172.16.0.14", "port":16020 } ] } ] } ] }
Spark任务提交任务的配置参数,主类,以及对应的参数
该参数主要为3个参数第一个为Phonix的链接,第二个为Phonix的表名称,第三个为传入的MaxCompute表
点击冒烟测试按钮,可以看到任务执行成功
在临时查询节点中执行查询语句,可以得到数据已经写入MaxCompute的表中
使用Spark on MaxCompute访问Phonix的数据,并将数据写入到MaxCompute的表中经过实践,该方案时可行的。但在实践的时有几点注意事项:
1.结合实际使用情况选择对应的Hbase以及Phonix版本,对应的版本一致,并且所使用的客户端,以及代码依赖都会有所改变。
2.使用公网在IEAD进行本地测试,要注意Hbase白名单,不仅要设置DataWorks的白名单,还需将自己本地的地址加入到白名单中。
3.代码打包时需要将pom中的依赖关系进行梳理,避免ODPS所存在的包在对应的依赖中,进而引起jar包冲突,并且打包时打成shaded包,避免缺失遗漏对应的依赖。
