Cheng Lian 1360a6d636 [SPARK-15112][SQL] Disables EmbedSerializerInFilter for plan fragments that change schema ... ## What changes were proposed in this pull request? `EmbedSerializerInFilter` implicitly assumes that the plan fragment being optimized doesn't change plan schema, which is reasonable because `Dataset.filter` should never change the schema. However, due to another issue involving `DeserializeToObject` and `SerializeFromObject`, typed filter *does* change plan schema (see [SPARK-15632][1]). This breaks `EmbedSerializerInFilter` and causes corrupted data. This PR disables `EmbedSerializerInFilter` when there's a schema change to avoid data corruption. The schema change issue should be addressed in follow-up PRs. ## How was this patch tested? New test case added in `DatasetSuite`.
