   after the sqoop yarn task finish, ds will check the yarn job info by rest 
api.
   
   if your yarn config in ds is not correct, the task res will not success
   
   ```
   # if resourcemanager HA enable, please type the HA ips ; if resourcemanager 
is single, make this value empty
   yarn.resourcemanager.ha.rm.ids=ip1,ip2
   resource.manager.httpaddress.port=8088
   # if resourcemanager HA enable or not use resourcemanager, please keep the 
default value; If resourcemanager is single, you only need to replace ds1 to 
actual resourcemanager hostname.
   yarn.application.status.address=http://xxx:8088/ws/v1/cluster/apps/%s
   ```
   
   xxx  in `yarn.application.status.address`  will replaced by active yarn 
resource manager in `yarn.resourcemanager.ha.rm.ids`
   
   ---
   when master stop the sqoop process ,the kill command send to the worker 
server, so the worker will kill the yarn job by rest api
