### Change Logs Currently when move a hudi table from schema1 to schema2 and then insert data with the old schema1, then schema 2 is kept for the whole table. This is not consistent with hive metastore which get its schema updated to the old schema1. Then this PR avoid update the hive schema when only missing columns are in the input data. This might only work as proposed here when reconcile = true see https://hudi.apache.org/docs/configurations#hoodiedatasourcewritereconcileschema ### Impact _Describe any public API or user-facing feature change or any performance impact._ **Risk level: none | low | medium | high** _Choose one.
