主机迁移后，服务状态变成 unhealthy

登陆主机中查看，现象：

nodemanager 进程不存在，/data/hadoop/logs 下无日志。
执行 /opt/spark/sbin/check-slave.sh，报错： node manager 未启动。
执行 /opt/spark/sbin/action-slave.sh，报错：node manager 已启动。

导致节点健康状态一直无法恢复。

恢复流程：

删除 /data/hadoop/pids/ 中 nodemanager 的 pid
执行 /opt/spark/sbin/action-slave.sh

需要在新版本中，复现并修复该问题。
