   > For example, killType = KILL_BY_ID will killl task by task id, killType = 
KiLL_BY_LOG will kill task by log content.
   
   Not only kill task need to read task log , for example whether SHELL task 
status success or failure ,
   first of all judge shell exit code  status , second judge for yarn or messos 
resources negotiator status . so necessary resources negotiator type to user 
choice
