Java 无法在ambari中重新启动纱线节点管理器

我是ambari和Thread的新手，我的新flash ambari机器没有任何其他配置

ambari版本是最新版本，以下是warn.py地址： ambari服务器/src/main/resources/common services/warn/2.1.0.2.0/package/scripts/warn.py

我已经找到了一些像这样的潜在解决方案，但是，它不起作用

我已经提供了日志目录的所有权限

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

---

命令：chmod 777/data/var/log/hadoop-thread/nodemanager/recovery-state/thread-nm-state/

您需要检查试图访问该文件的用户是谁。很可能是“纱线”用户。在Ambari计算机上运行以下命令

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

---

如果可行，您也可以尝试检查nodemanager输出和日志文件以了解更多信息。

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：

将用户和组更改为纱线：

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

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

将权限更改为755:

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

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

---

检查/数据权限。当您尝试更改权限时，不要忘记使用“-R”。示例：

chmod-R 655/数据
