> SPARK-12321 add a framework based on reflection that can serialize
> {{TreeNode}} to JSON and deserialize it back. However, it can't handle all
> corner cases and we bypass them in the test, see
> https://github.com/apache/spark/pull/10311/files#diff-238d584c15e16c24f49a40bcf163fe13R190
> and
> https://github.com/apache/spark/pull/10311/files#diff-238d584c15e16c24f49a40bcf163fe13R212.
> known corner cases:
> 1. ExpressionEncoder
> 2. BaseRelation
> 3. hive logical plan
> 4. physical plan
> The framework is in catalyst module and may not be able to handle corner
> cases from other modules, an idea is defining a {{JsonSerializable}} trait
> and implement it for corner cases.
