**How does ds gets task logs and determine whether task failes or successed
?**
I have 3 type of tasks—— datax、impala、hive，all of them are sealed in shell
scripts.
When ds call these scripts,datax and impala task successed,but hive task
failed.
This phenomenon confuse me.
I have asked why this happend in ds groups,and someone thell me to config
yarn parameter in the $dolphinscheduler_home/conf/common.properties,because ds
determine whether **hive** task is failed or successed by yarn result.
1. Now, I'm wondering how does ds determine whether **datax** and **impala**
task is failed or successed?
2. And, how does ds gets logs of different type tasks,such as
**datax**、**impala**、**hive**?
**Which version of DolphinScheduler:**
-[1.3.3]
