   first, if the task self exit code == 0, it means this task runs successfully, at the same time ,if this task is also a yarn task, we will also get the yarn result through the yarn restful api which setting in the common.properties
   ```
   # if resourcemanager HA enable, please type the HA ips ; if resourcemanager is single, make this value empty
   yarn.resourcemanager.ha.rm.ids=192.168.xx.xx,192.168.xx.xx
   
   # 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://ds1:8088/ws/v1/cluster/apps/%s
   # job history status url when application number threshold is reached(default 10000,maybe it was set to 1000)
   yarn.job.history.status.address=http://ds1:19888/ws/v1/history/mapreduce/jobs/%s
   ```
   
   so if the task is yarn task , these two result will determine the final result
