【原创】大数据基础之Ambari（3）通过Ambari部署Airflow

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

Jan 18 19:04:05 cdp-test-server-01.bj python[15246]: detected unhandled Python exception in '/var/lib/ambari-agent/cache/common-services/AIRFLOW/1.10.0/package/scripts/airflow_worker_control.py'

可以通过修改配置解决

# grep ProcessUnpackaged /etc/abrt/abrt-action-save-package-data.conf
no

改为yes
