官方：http://ambari.apache.org/
The Apache Ambari project is aimed at making Hadoop management simpler by developing software for provisioning, managing, and monitoring Apache Hadoop clusters. Ambari provides an intuitive, easy-to-use Hadoop management web UI backed by its RESTful APIs.
ambari通过web UI使得Hadoop管理更加简单，覆盖安装、管理和监控等方面；
Ambari enables System Administrators to:
- Provision a Hadoop Cluster
- Ambari provides a step-by-step wizard for installing Hadoop services across any number of hosts.
- Ambari handles configuration of Hadoop services for the cluster.
- Manage a Hadoop Cluster
- Ambari provides central management for starting, stopping, and reconfiguring Hadoop services across the entire cluster.
- Monitor a Hadoop Cluster
- Ambari provides a dashboard for monitoring health and status of the Hadoop cluster.
- Ambari leverages Ambari Metrics System for metrics collection.
- Ambari leverages Ambari Alert Framework for system alerting and will notify you when your attention is needed (e.g., a node goes down, remaining disk space is low, etc).
功能包括：安装向导、集群配置、各个组件的启动停止和配置更新、监控页面、指标收集、报警等；
Ambari enables Application Developers and System Integrators to:
- Easily integrate Hadoop provisioning, management, and monitoring capabilities to their own applications with the Ambari REST APIs.
一 安装
官方安装指南：https://cwiki.apache.org/confluence/display/AMBARI/Installation+Guide+for+Ambari+2.7.3
1 下载编译打包
# wget http://www.apache.org/dist/ambari/ambari-2.7.3/apache-ambari-2.7.3-src.tar.gz
# tar xfvz apache-ambari-2.7.3-src.tar.gz
# cd apache-ambari-2.7.3-src
# mvn versions:set -DnewVersion=2.7.3.0.0# pushd ambari-metrics
# mvn versions:set -DnewVersion=2.7.3.0.0
# popd# mvn -B clean install rpm:rpm -DnewVersion=2.7.3.0.0 -DbuildNumber=4295bb16c439cbc8fb0e7362f19768dde1477868 -DskipTests -Dpython.ver="python >= 2.6"
最后一步要build很久（里边的坑不少，还与网络情况有关，要反复执行多遍，后续执行建议将clean去掉，节省时间，估计至少要1天），并且可能出现多种报错，详见附录；

有好几个jar下载过程可能很慢或者报超时错误和连接被重置，这时要么换个环境手工下载后放到maven local repository，要么直接重试；
3）编译错误

这是因为你使用了jdk11，因为java.xml.bind (JAXB) 在11中 REMOVED，改用11之前的jdk版本即可；
Java 8 - OK
Java 9 - DEPRECATED

这个看不出直接原因，错误是因为执行python返回1，具体的错误没报出来，只能手工重现问题；
首先看报错的脚本：
# cat /data/apache-ambari-2.7.3-src/ambari-metrics/ambari-metrics-host-monitoring/target/antrun/build-psutils-compile.xml
<?xml version="1.0" encoding="UTF-8" ?>
<project name="maven-antrun-" default="psutils-compile" >
<target name="psutils-compile">
<exec failonerror="true" dir="/data/apache-ambari-2.7.3-src/ambari-metrics/ambari-metrics-host-monitoring/src/main/python/psutil" executable="/data/apache-ambari-2.7.3-src/ambari-metrics/ambari-metrics-host-monitoring/../../ambari-common/src/main/unix/ambari-python-wrap">
<arg value="setup.py"/>
<arg value="build"/>
<arg value="--build-platlib"/>
<arg value="/data/apache-ambari-2.7.3-src/ambari-metrics/ambari-metrics-host-monitoring/target/psutil_build"/>
</exec>
</target>
</project>
然后手工重现：
# cd /data/apache-ambari-2.7.3-src/ambari-metrics/ambari-metrics-host-monitoring/src/main/python/psutil
# /data/apache-ambari-2.7.3-src/ambari-metrics/ambari-metrics-host-monitoring/../../ambari-common/src/main/unix/ambari-python-wrap setup.py build --build-platlib /data/apache-ambari-2.7.3-src/ambari-metrics/ambari-metrics-host-monitoring/target/psutil_build

终于看到直接原因了，缺少gcc（你的原因可能不同，手工执行可以看到）
yum install gcc
