>                 Key: HUDI-1314
>                 URL: https://issues.apache.org/jira/browse/HUDI-1314
>             Project: Apache Hudi
>          Issue Type: Bug
>          Components: Testing
>    Affects Versions: 0.5.1
>            Reporter: Basanth Roy
>            Priority: Minor
>   Original Estimate: 2h
>  Remaining Estimate: 2h
>
> In the Hudi Test Suite, the DagUtils class currently has these 2 utility methods w.r.t the DagNode
>  # Java Object to String (convertDagToYaml)
>  # String to Java Object (convertJsonToDagNode)
> However , these 2 methods are incompatible with each other. That is, the output of the first one cannot be used as the input to the second one. That is a bug. And the root cause is the way ObjectMapper handles null node values. It currently writes them as null into the String representation. 
>  
> Since root node has no dependencies, the convertJsonToDagNode should handle that case
