Ambari是Hadoop集群的一个管理服务，很多时候如果需要定制自己的Hadoop发行版或者开发Hadoop云服务的时候，就需要涉及到一些自定义的开发，这个时候可能就会使用到Ambari。
Ambari开发语言以Java和Py为主，同时还有大量的shell脚本，因为Ambari最终生成的是对应的机器的安装包，所以需要考虑一下自己的编译环境，工程默认提供了一个基于centos的docker编译环境，可以通过start-build-env.sh脚本进入环境。该脚本是将本地的环境，例如mvn，java以及源码工程目录挂载到docker容器中。
编译准备 源码地址：https://github.com/apache/ambari.git
在编译之前，需要先设置参数：
mvn versions:set-property -Dproperty=revision -DnewVersion=2.7.5
因为我本次是基于master代码，最新是2.7.5的正式版，所以使用了这个版本，确定版本后，通过如下代码进行编译：
mvn -B clean install package rpm:rpm -DnewVersion=2.7.5 -DskipTests -Drat.skip -Dpython.ver="python >= 2.6" -Preplaceurl
-Drat.skip参数是为了跳过licensing 检查,防止报错Too many files with unapproved license

碰到这个问题是因为代码里面指定的node版本和环境设置的版本不一致，可以由多种解决办法，我使用的最简单的一种就是修改ambari-admin工程里面的exec-maven-plugin插件，将：
<argument>${basedir}/src/main/resources/ui/admin-web/node_modules/bower/bin/bower</argument>
替换成：
<argument>bower</argument>
也可以修改pom文件中的nodeVersion和npmVersion，查看环境中的版本号，例如做如下配置：
<!--修改ambari-admin模块下的pom.xml文件 --> <nodeVersion>3.10.10</nodeVersion> <npmVersion>v6.17.1</npmVersion>
这样的话也能解决问题。
下载路径问题 Ambari的监控部分需要依赖Hbase等组件作为存储，默认会使用HDP的官方网站的地址进行下载，因为该地址已经失效，我就将其修改为了Apache的下载地址，修改ambari-metrics-timelineservice工程下的pom文件中的properties部分：
<!--TODO change to HDP URL--> <hbase.tar>https://archive.apache.org/dist/hbase/2.0.2/hbase-2.0.2-bin.tar.gz</hbase.tar> <hbase.folder>hbase-2.0.2.3.1.4.0-315</hbase.folder> <hadoop.tar>https://archive.apache.org/dist/hadoop/core/hadoop-3.1.1/hadoop-3.1.1.tar.gz</hadoop.tar> <hadoop.folder>hadoop-3.1.1.3.1.4.0-315</hadoop.folder> <grafana.folder>grafana-6.4.2</grafana.folder> <grafana.tar>https://dl.grafana.com/oss/release/grafana-6.4.2.linux-amd64.tar.gz</grafana.tar> <phoenix.tar>https://downloads.apache.org/phoenix/apache-phoenix-5.0.0-HBase-2.0/bin/apache-phoenix-5.0.0-HBase-2.0-bin.tar.gz</phoenix.tar> <phoenix.folder>phoenix-5.0.0.3.1.4.0-315</phoenix.folder>
将对应的key修改为上面的内容，即可下载对应的二进制包。
同时因为Ambari默认会使用HDP的maven rep去下载hbase，phoenix等依赖的jar，该maven rep里面也下架了相关的依赖，所以需要修改对应的版本让其默认从apache maven rep中进行下载：
<properties> <!-- Needed for generating FindBugs warnings using parent pom --> <!--<yarn.basedir>${project.parent.parent.basedir}</yarn.basedir>--> <protobuf.version>2.5.0</protobuf.version> <hadoop.version>3.1.1</hadoop.version> <phoenix.version>5.0.0-HBase-2.0</phoenix.version> <hbase.version>2.0.2</hbase.version> </properties>
调整对应依赖的版本如上图所示，即可，中间大部分问题都会聚焦在版本的对应上，最后编译成功：

找到对应的包进行安装就行。
安装包在~/src/ambari-server/target/rpm/ambari-server/RPMS/x86_64目录下，使用yum install ambari-server*.rpm进行安装，进行安装的时候可能会碰到：
centos7:~/src/ambari-server/target/rpm/ambari-server/RPMS/x86_64 $ yum install ambari-server*.rpm Loaded plugins: fastestmirror, ovl ovl: Error while doing RPMdb copy-up: [Errno 13] Permission denied: '/var/lib/rpm/Triggername' You need to be root to perform this command. centos7:~/src/ambari-server/target/rpm/ambari-server/RPMS/x86_64 $ sudo yum install ambari-server*.rpm bash: sudo: command not found
安装权限不够，sudo也不存在，这时候可以使用root的权限重新进入容器：
docker exec -u root -i -t 64814ad3cd7b /bin/bash
再进行安装即可。
上面安装的是ambari server，还需安装agent，对应的包在ambari-agent/target/rpm/ambari-agent/RPMS/x86_64/ambari-agent-2.6.2.0-0.x86_64.rpm下，安装同理。
