ambari2.7.3（hdp3.1） 安装 airflow1.10
ambari的hdp中原生不支持airflow安装，下面介绍如何通过mpack方式使ambari支持airflow安装：
1 下载
# wget https://github.com/miho120/ambari-airflow-mpack/raw/master/airflow-service-mpack.tar.gz
2 安装
# ambari-server install-mpack --mpack airflow-service-mpack.tar.gz --verbose
3 重启
# ambari-server restart
4 ambari页面没有出现ambari，检查mpack.json
/var/lib/ambari-server/resources/mpacks/airflow-ambari-mpack-1.5.4/mpack.json
"service_versions_map": [
{
"service_name" : "AIRFLOW",
"service_version" : "1.10.0",
"applicable_stacks" : [
{
"stack_name" : "HDP",
"stack_version" : "2.4"
},
{
"stack_name" : "HDP",
"stack_version" : "2.5"
},
{
"stack_name" : "HDP",
"stack_version" : "2.6"
},
{
"stack_name" : "HDP",
"stack_version" : "3.0"
}
]
}
]
需要增加HDP3.1，修改完重新打包
4 卸载
ambari-server uninstall-mpack --mpack-name=airflow-ambari-mpack
5 安装（同上）
6 重启（同上）
打开ambari页面
启动worker时可能失败，查看启动命令
2019-01-18 19:09:48,159 - Execute['service airflow-worker start'] {}
查看日志
journalctl -xe
发现有报错

可以通过修改配置解决
# grep ProcessUnpackaged /etc/abrt/abrt-action-save-package-data.conf
no
改为yes
