---------------------------------
Summary: Hudi Test Suite : Root node has no dependencies. DagUtils
should consider that
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
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
