我是新的蜜蜂Ambari和Yarn，我没有任何其他配置为我的新闪光Ambari机。
ambari版本是最新的，下面是yarn.py地址：ambari server/src/main/resources/common services/yarn/2.1.0.2.0/package/scripts/yarn.py
我找到了一些有潜力的解决办法，https://community.hortonworks.com/questions/11907/nodemanager-fails-to-start-io-error-lock.html 以及https://reviews.apache.org/r/38098/diff/1/但是，它不起作用。
我提供了日志目录的所有权限。

尝试将/data/var/log/hadoop yarn/nodemanager/recovery state/yarn nm state/this文件的权限更改为700甚至777
命令：chmod 777/data/var/log/hadoop-yarn/nodemanager/recovery-state/yarn-nm-state/

您需要检查试图访问该文件的用户是谁。很可能是“Yarn”用户。在ambari机器上运行以下命令

sudo chown -R yarn:yarn /data/var/log/hadoop-yarn

如果它能工作的话，您就可以尝试检查nodemanager输出和日志文件以获取更多信息。

首先尝试检查权限：

ls -l /data/var/lib/ | grep hadoop

在您的案例中，您会发现如下内容：

d---------. 4    root         root          44 Apr 5 09:45 hadoop-yarn

你必须做两件事：
将用户和组更改为：

chown -R yarn:yarn data/var/log/hadoop-yarn

将权限更改为755:

chmod -R 755 data/var/log/hadoop-yarn
