> In SchemaMergingUtils#getLeastCommonType, the merge result of BIGINT and DOUBLE is STRING now.
> However, considering JSON string, JSON number can be integers or floating point. Data type of integers can be inferred as BIGINT, and floating point can be inferred as DOUBLE. So a JSON number field will be inferred as STRING, which is confusing.
