   @Yanwenjingcn 
   I encountered the same error like yours when I was stopping  a task that's the type of shell.

   ---------------------
   
   Cause:
     This error should be caused by missing the command of pstree in your OS. 
     
   Solution:
     You need to install it in your OS. Next line maybe useful for you:
     sudo  yum -y install psmisc
