我在Apache hadoop群集上使用apache nifi，当我尝试启动run-start.sh文件时，出现以下错误。
环境：Windows
2018-08-23 20:00:31,856 WARN [main] org.apache.nifi.bootstrap.Command Failed to set permissions so that only the owner can read pid file D:\NIFI\nifi-1.7.1-bin\nifi-1.7.1\bin\.
.\run\nifi.pid; this may allows others to have access to the key needed to communicate with NiFi. Permissions should be changed so that only the owner can read this file

，并且无法从正面连接。当我关闭并尝试重新连接时，会发生这种情况。我通常会在Windows上使用ctrl + _c停止服务器。
请帮助
