Apache Hudi项目编译

前置环境

环境	版本
java	1.8.0_271
maven	3.8.5
scala	2.12

拉取Hudi源码

git clone https://github.com/apache/hudi.git

使用IDEA打开hudi项目将分支切换到 release-0.12.0

修改hudi项目的pom.xml文件添加加速依赖

<repository>
        <id>nexus-aliyun</id>
        <name>nexus-aliyun</name>
        <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>

修改依赖的组件版本

<hadoop.version>3.1.3</hadoop.version>
<hive.version>3.1.2</hive.version>

打包命令

mvn clean package -DskipTests -Dspark3.2 -Dflink1.13 -Dscala-2.12 -Dhadoop.version=3.1.3 -Pflink-bundle-shade-hive3

修改源码适配Hadoop3.X

Hudi默认依赖的hadoop2，要兼容hadoop3，除了修改版本，HoodieParquetDataBlock，这里需要传入两个参数因此我们将地119行修改为

    try (FSDataOutputStream outputStream = new FSDataOutputStream(baos,null)) {
      try (HoodieParquetStreamWriter<IndexedRecord> parquetWriter = new HoodieParquetStreamWriter<>(outputStream, avroParquetConfig)) {
        for (IndexedRecord record : records) {
          String recordKey = getRecordKey(record).orElse(null);
          parquetWriter.writeAvro(recordKey, record);
        }
        outputStream.flush();
      }
    }

解决Jetty冲突

原因：Hive版本为3.1.2，其携带的jetty是0.9.3，hudi本身用的0.9.4，存在依赖冲突。

修改 hudi-0.12.0/packaging/hudi-spark-bundle/pom.xml 在382行的位置，修改如下
