      Description

      YARN-3409 introduces placement constraint, Currently SLS does not support specify placement constraint. 

      YARN-8007 support specifying placement constraint for task containers in SLS. But there are still 

      some room for improvement:

      1. YARN-8007 only support placement constraint for the jobs level. In fact, the more flexible way is support placement constraint for the tasks level.
      2. In most scenarios, node itself has some characteristics, called attribute, which is not supported in SLS. So we can add the attribute on Nodes.
      3. YARN-8007 use the SYNTH as schedulingrequest input. But SYNTH can't create a large number of specific resource requests. We wanna create a new schedulingrequest input format(like sis format) for the more authentic input. We can add some field in sis format, and this is schedulingrequest input format.
