Review Comment:
   `ExecutionJobVertex#inputs` is `@Nullable`, but 
`ExecutionJobVertex#getInputs` is not since`getInputs()` checked the  
isInitialized(), and inputs never be null once is isInitialized.
   
   ```
       public List<IntermediateResult> getInputs() {
           checkState(isInitialized());
           return inputs;
       }
   ```
   
   WDYT?
