psutils-compile错误

build的时候报错：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (psutils-compile) on project ambari-metrics-host-monitoring: An Ant BuildException has occured: exec returned: 1

根据该错误信息，打开xml文件：

<?xml version="1.0" encoding="UTF-8" ?>
<project name="maven-antrun-" default="psutils-compile"  >
<target name="psutils-compile">
<exec failonerror="true" dir="/root/apache-ambari-2.4.2-src/ambari-metrics/ambari-metrics-host-monitoring/src/main/python/psutil" executable="/root/apache-ambari-2.4.2-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="/root/apache-ambari-2.4.2-src/ambari-metrics/ambari-metrics-host-monitoring/target/psutil_build"/>
</exec>
</target>
</project>

带上参数执行了一下wrap：

[root@bluejoe0 apache-ambari-2.4.2-src]# /root/apache-ambari-2.4.2-src/ambari-metrics/ambari-metrics-host-monitoring/../../ambari-common/src/main/uniython-wrap setup.py build --build-platlib /root/apache-ambari-2.4.2-src/ambari-metrics/ambari-metrics-host-monitoring/target/psutil_build

类似这样的错误，在网上查了一下，告知需要安装python-devel版本，因此：

yum install python-devel.x86_64

然后再重新build，问题消失了！！

buildNumber问题

ambari-agent start
/usr/sbin/ambari-agent: line 23: buildNumber: unbound variable

个人判断这是安装程序的bug，打开ambari-agent脚本，把${buildNumber}换成一个数字如：2.4.0.0即可。
