> HDFS balancer process start failed owing to daemon pid file is not cleared in some exception senario, but there is no useful information in log to trouble shoot as below.

> //代码占位符
> hadoop_error "${daemonname} is running as process $(cat "${daemon_pidfile}")
> {code}
> but actually, the process is not running as the error msg details above.
> Therefore, some more explicit information should be print in error log to guide users to clear the pid file and where the pid file location is.
