> Someimes we want to change the log level of executor when our application has
> already deployed, to see detail infomation or decrease the log items.
> Changing the log4j configure file is not convenient,so We add the ability to
> set log level settings for a running executor. It can also reverts the log
> level back to what it was before you added the setting.
