1. IDEA中创建hadoop项目

要配置了winutils

  1. 创建maven项目

  2. 添加依赖

    1. <dependencies>
    2.  <dependency>
    3.      <groupId>junit</groupId>
    4.      <artifactId>junit</artifactId>
    5.      <version>4.12</version>
    6.  </dependency>
    7.  <dependency>
    8.      <groupId>org.apache.logging.log4j</groupId>
    9.      <artifactId>log4j-slf4j-impl</artifactId>
    10.      <version>2.12.0</version>
    11.  </dependency>
    12.  <dependency>
    13.      <groupId>org.apache.hadoop</groupId>
    14.      <artifactId>hadoop-client</artifactId>
    15.      <version>3.1.3</version>
    16.  </dependency>
    17. </dependencies>

  1. 在main的resources 新建 log4j2.xml

    1. <?xml version="1.0" encoding="UTF-8"?>
    2. <Configuration status="error" strict="true" name="XMLConfig">
    3.  <Appenders>
    4.      <!-- 类型名为Console，名称为必须属性 -->
    5.      <Appender type="Console" name="STDOUT">
    6.          <!-- 布局为PatternLayout的方式，
    7.          输出样式为[INFO] [2018-01-22 17:34:01][org.test.Console]I'm here -->
    8.          <Layout type="PatternLayout"
    9.                  pattern="[%p] [%d{yyyy-MM-dd HH:mm:ss}][%c{10}]%m%n"/>
    10.      </Appender>
    11.  </Appenders>
    13.  <Loggers>
    14.      <!-- 可加性为false -->
    15.      <Logger name="test" level="info" additivity="false">
    16.          <AppenderRef ref="STDOUT"/>
    17.      </Logger>
    19.      <!-- root loggerConfig设置 -->
    20.      <Root level="info">
    21.          <AppenderRef ref="STDOUT"/>
    22.      </Root>
    23.  </Loggers>
    24. </Configuration>
