   ### Search before asking
   
   - [X] I had searched in the 
[issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and 
found no similar issues.
   
   
   ### Description
   
   In Nereids, we use physical plan to describe query plan. But in original 
Doris, we use Fragment to do that.
   So, we need to translate physical plan into Fragment.
   
   
   ### Solution
   
   Maybe we should implement this in two phase.
   First, some rules that translate each type physical plan node to PlanNode in 
Fragment
   Second, a node type independent framework that assemble PlanNodes to 
Fragments according to physical plan node structure.
