flink1.12.x 打包pom.xml，yarn方式运行（socket案例）

修改pom.xml

不包含flink自带包

flink自带的jar包，在依赖上要添加 <scope>provided</scope>，打包时，不要包含这些包

<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-java</artifactId>
    <version>${flink.version}</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-streaming-java_2.12</artifactId>
    <version>${flink.version}</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-clients_2.12</artifactId>
    <version>${flink.version}</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.30</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.7.30</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
    <scope>provided</scope>
</dependency>

注意

flink-runtime-web_2.12 要设置 <scope>provided</scope>

<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-runtime-web_2.12</artifactId>
    <version>${flink.version}</version>
    <scope>provided</scope>
</dependency>

注意

org.apache.bahir 不要用，因为是 scala 2.11 版本，与 flink 中的scala 2.12 版不匹配

<dependency>
    <groupId>org.apache.bahir</groupId>
    <artifactId>flink-connector-redis_2.11</artifactId>
    <version>1.0</version>
</dependency>

添加打包插件

log4j.properties

在 resources 目录下创建 log4j.properties 文件，内容如下：

# DEBUG 级别，即：所有信息都会输出
log4j.rootLogger=INFO, stdout
# 配置 stdout，输出到控制台
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

注意：不加此文件会显示警告

测试

打包

双击 maven 的 package，打包，结果有2个 jar 文件，一个文件比较大，这个文件就是打包好的文件

启动 socket

登录 hadoop1，执行下面命令：

nc -lk 9999

上传

略

per-job cluster模式启动

/program/flink-1.12.5/bin/flink run -m yarn-cluster -ytm 1000 -yjm 1000 -ys 1  -c  map.TestSocket    /program/flink-1.0-SNAPSHOT.jar

看到下图表示启动成功：

输入数据

在 socket 窗口输入下面内容：

haha hehe
xixi haha xixi
