Question

我使用的是HDP 2.4.2，之前我安装过zeppelin服务器。它工作正常但今天当我重新启动集群（重新启动AWS节点）时，Ambari显示Zeppelin服务器未运行且无法启动服务器，并出现以下错误：

Traceback (most recent call last):

cat: /var/run/zeppelin-notebook/zeppelin-zeppelin-ip-10-0-0-11.eu-west-1.compute.internal.pid: No such file or directory

在zeppelin日志中：

ERROR [2016-06-06 03：20：36,714]（{main} VFSNotebookRepo.java [list]：140） - 无法读取备注文件：/// usr / hdp / current / zeppelin-server / lib / notebook / screenshots java.io.IOException：file：///usr/hdp/current/zeppelin-server/lib/notebook/screenshots/note.json not found

但由于某种原因，zeppelin端口正在侦听，尽管存在这些错误，但zeppelin服务器运行正常并执行所有查询。请告知如何纠正Ambari中的问题并在没有错误的情况下启动服务。

Answer 1

问题在于zeppelin服务的PID文件。它由错误的用户拥有或具有错误的权限。手动停止zeppelin服务，然后删除位于/var/run/zeppelin-notebook/zeppelin-zeppelin-ip-10-0-0-11.eu-west-1.compute.internal.pid的pid文件。同时仔细检查/var/run/zeppelin-notebook文件夹上的所有者/权限。然后，您应该能够在Ambari UI中重新启动该服务。

Ambari显示zeppelin服务器未启动但服务器实际启动并运行
