Ambari 启动异常 ambari_commons.exceptions.FatalException

背景

昨天公司机房停电， 没来得及关服务器， 早上到公司发现Ambari环境无法启动了

异常信息

[root@node1 ~]# service ambari-server status
Using python  /usr/bin/python
Ambari-server status
ERROR: Could not create . Reason: [Errno 2] No such file or directory: ''
Traceback (most recent call last):

    raise FatalException(-1, "Unable to access {0} directory. Confirm the directory is created and is writable by Ambari Server user account '{1}'".format(directory, getpass.getuser()))
ambari_commons.exceptions.FatalException: "Fatal exception: Unable to access  directory. Confirm the directory is created and is writable by Ambari Server user account 'root', exit code -1"

异常原因

1. 先查看 ambari.properties

[root@node1 ~]# find / -name ambari.properties
/etc/ambari-server/conf/ambari.properties 
[root@node1 ~]# cat /etc/ambari-server/conf/ambari.properties 
[root@node1 ~]#

解决办法

1. 可以找其他的 ambari.properties 替换到当前文件夹中
2. 使用 ambari-server setup 重新设置环境

我这里没有找到 ambari.properties 配置文件， 是使用 ambari-server setup 配置了环境

重新启动

[root@node1 conf]# ambari-server status
Using python  /usr/bin/python
Ambari-server status
Ambari Server not running.
[root@node1 conf]# ambari-server start
