1.2 配置Maven阿里云仓库

1.2.1 配置setting.xml

1. 配置本地仓库位置
   

   <!-- 本地仓库位置 -->
   <localRepository>/Users/mo/Maven/m2/repository</localRepository>

2. 添加阿里云仓库
   

   <!-- 阿里镜像仓库 -->
       <mirror>
           <id>alimaven</id>
           <mirrorOf>central</mirrorOf>
           <name>aliyun maven</name>
           <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
       </mirror>
   
       <mirror>
           <id>nexus-aliyun</id>
           <mirrorOf>central</mirrorOf>
           <name>Nexus aliyun</name>
           <url>http://maven.aliyun.com/nexus/content/groups/public</url>
       </mirror>
   
       <mirror>
           <id>central</id>
           <name>Maven Repository Switchboard</name>
           <url>http://repo1.maven.org/maven2/</url>
           <mirrorOf>central</mirrorOf>
       </mirror>
   
       <mirror>
           <id>repo2</id>
           <mirrorOf>central</mirrorOf>
           <name>Human Readable Name for this Mirror.</name>
           <url>http://repo2.maven.org/maven2/</url>
       </mirror>
   
       <mirror>
           <id>ibiblio</id>
           <mirrorOf>central</mirrorOf>
           <name>Human Readable Name for this Mirror.</name>
           <url>http://mirrors.ibiblio.org/pub/mirrors/maven2/</url>
       </mirror>
   
       <mirror>
           <id>jboss-public-repository-group</id>
           <mirrorOf>central</mirrorOf>
           <name>JBoss Public Repository Group</name>
           <url>http://repository.jboss.org/nexus/content/groups/public</url>
       </mirror>
   
       <mirror>
           <id>mirrorId</id>
           <mirrorOf>repositoryId</mirrorOf>
           <name>Human Readable Name for this Mirror.</name>
           <url>http://my.repository.com/repo/path</url>
       </mirror>
   
      </mirrors>

1.3 创建HBase Project

1.3.1 配置IDEA Maven 路径

1.3.2 配置项目pom.xml

1. 官方参考配置链接：https://docs.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_cdh_6_maven_repo.html
   示例：pom.xml
   

   <?xml version="1.0" encoding="UTF-8"?>
   <project xmlns="http://maven.apache.org/POM/4.0.0"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
       <modelVersion>4.0.0</modelVersion>
   
       <groupId>com.cdhHbase</groupId>
       <artifactId>cdhHbase</artifactId>
       <version>1.0-SNAPSHOT</version>
   
       <repositories>
           <repository>
               <id>cloudera</id>
               <url>https://repository.cloudera.com/artifactory/cloudera-repos/</url>
           </repository>
       </repositories>
   
       <properties>
           <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
           <hadoop.version>3.0.0-cdh6.2.0</hadoop.version>
           <hbase.version>2.1.0-cdh6.2.0</hbase.version>
       </properties>
   
       <dependencies>
           <dependency>
               <groupId>org.apache.hadoop</groupId>
               <artifactId>hadoop-client</artifactId>
               <version>${hadoop.version}</version>
           </dependency>
   
           <dependency>
               <groupId>org.apache.hbase</groupId>
               <artifactId>hbase-server</artifactId>
               <version>${hbase.version}</version>
           </dependency>
   
           <dependency>
               <groupId>org.apache.hbase</groupId>
               <artifactId>hbase-client</artifactId>
               <version>${hbase.version}</version>
           </dependency>
       </dependencies>
   
   </project>

1.3.3 拷贝CDH相关的配置文件

1. 将Hadoop的core-site.xml以及Hbase的hbase-site.xml复制到项目的src/main/resources目录下（CDH 版的相关配置文件在/etc/{module}下）
2. 在项目的src/main/resources目录下创建log4j.properties文件（防止日志报红）
   示例：log4j.properties
   

   log4j.rootLogger=INFO, stdout
   log4j.appender.stdout=org.apache.log4j.ConsoleAppender
   log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
   log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n
   log4j.appender.logfile=org.apache.log4j.FileAppender
   log4j.appender.logfile.File=target/spring.log
   log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
   log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n

    

3. OK, Enjoy it.
