cloudera-scm-server dead but pid file exists

原因：CDH没有正常关闭，直接管的集群，再次启动时报错。

[root@hadoop102 commands]# /opt/module/cm/cm-5.16.2/etc/init.d/cloudera-scm-server status
cloudera-scm-server dead but pid file exists

解决方法：删除pid文件，重新启动。
pid 所在路径为：[root@hadoop102 proc]# cd /opt/module/cm/cm-5.16.2/run/

[root@hadoop102 proc]# cd /opt/module/cm/cm-5.16.2/run/
[root@hadoop102 run]#
[root@hadoop102 run]# ll
