初步看，这个任务是在mo server还未初始化时，就开始执行了。此时global pu还未初始化

[xzxiong]

root cause:
StorageUsage task 由 task service 发起运行，在 initMOServer 初始化 setGlobalPu 前，所以调用 getGlobalPu 失败。

启动顺序

1. getHAKeeperClient 开始接收 heartbeat，触发 task service开始工作
2. initMOServer 调用 setGlobalPu
   

启动日志

MOServer 未完成初始化
注: MOServer 启动时会打印日志 Server Listening ...
