直接从github拉取flink-1.10.1版本代码
git clone -b release-1.10.1 https://github.com/apache/flink.git

flink-1.10.1修复了1.10中158处bug,并进行了优化。
官方也是强烈建议所有用户升级到1.10.1。

废话不多说,直接进入正题,开始flink-1.10.1版本的源码编译。

编译环境需要提前准备好maven和java。
最简单的编译命令如下:
mvn clean install -DskipTests

如果想加快源码编译进度,可以在编译过程中跳过tests、QA插件、文档等
编译命令如下:
mvn clean install -DskipTests -Dfast

这两种方式说的都是不考虑flink与Hadoop整合的使用场景。
如果需要与Hadoop整合使用,需要提供hadoop classes依赖。
这里有两种方式:
方式1:将hadoop classpath添加到flink。这种方式工作量比较小,简单方便,但是hadoop class依赖众多,可能与flink class有jar冲突的情况
方式2:直接将Hadoop classes依赖打包放置到flink/lib文件夹下
官方有打好的几个hadoop版本对应的包
Pre-bundled Hadoop 2.4.1:https://repo.maven.apache.org/maven2/org/apache/flink/flink-shaded-hadoop-2-uber/2.4.1-10.0/flink-shaded-hadoop-2-uber-2.4.1-10.0.jar
Pre-bundled Hadoop 2.6.5:https://repo.maven.apache.org/maven2/org/apache/flink/flink-shaded-hadoop-2-uber/2.6.5-10.0/flink-shaded-hadoop-2-uber-2.6.5-10.0.jar
Pre-bundled Hadoop 2.7.5:https://repo.maven.apache.org/maven2/org/apache/flink/flink-shaded-hadoop-2-uber/2.7.5-10.0/flink-shaded-hadoop-2-uber-2.7.5-10.0.jar
Pre-bundled Hadoop 2.8.3:https://repo.maven.apache.org/maven2/org/apache/flink/flink-shaded-hadoop-2-uber/2.8.3-10.0/flink-shaded-hadoop-2-uber-2.8.3-10.0.jar
当然,如果这里没有你需要的hadoop版本,你就得自己打包了。
打包需要使用另外一个项目:flink-shaded
git clone -b release-9.0 https://github.com/apache/flink-shaded.git
注意:这里一定要使用9.0,因为flink-1.10.1项目中依赖的为9.0
flink-release-1.10.1\flink-release-1.10.1\pom.xml中可以查看或者更改版本
<flink.shaded.version>9.0</flink.shaded.version>
编译打包命令:
mvn clean install -Dhadoop.version=3.0.0
注意:如果需要指定hadoop的发行商,需要使用-Pvendor-repos。当然前提是maven仓库增加了对应发行商的仓库地址,详见https://maven.apache.org/guides/mini/guide-multiple-repositories.html
如:mvn clean install -Pvendor-repos -Dhadoop.version=3.0.0-cdh6.2.0


















执行上述步骤,将打好的包flink-shaded-hadoop-2-uber-3.0.0-9.0.jar拷贝到flink/lib文件夹下
