[HUDI-4588][HUDI-4472] Addressing schema handling issues in the write path (#6358)
Currently, HoodieParquetReader is not specifying projected schema properly when reading Parquet files which ends up failing in cases when the provided schema is not equal to the schema of the file being read (even though it might be a proper projection, ie subset of it), like in common CDC case when column is being dropped from the RDS and the schema of the new batch is lacking the old column.
To address the original issue described in HUDI-4588, we also have to relax the constraints imposed by TableSchemaResolver.isSchemaCompatible method not allowing columns to be evolved by the way of dropping columns.
After addressing the original problem a considerable amount of new issues have been discovered including following:
- Writer's schemas were deduced differently for different flows (for ex, Bulk Insert vs other ops)
- Writer's schema was not reconciled against table's schemas in terms of nullability (this is asserted w/in AvroSchemaConverter, that is now invoked as part of the projection)
- (After enabling schema validations) Incorrect schema handling w/in HoodieWriteHandle has been detected (there were 2 ambiguous schema references, set incorrectly, creating confusion)
- (After enabling schema validations) Incorrect schema handling w/in MergeHelper impls, where writer's schema was used as a existing file's reader-schema (failing in cases when these 2 diverge)
Changes:
- Adding missing schema projection when reading Parquet file (using AvroParquetReader)
- Relaxing schema evolution constraints to allow columns to be dropped
- Revisiting schema reconciliation logic to make sure it's coherent
- Streamlining schema handling in HoodieSparkSqlWriter to make sure it's uniform for all operations (it isn't applied properly for Bulk-insert at the moment)
- Added comprehensive test for Basic Schema Evolution (columns being added, dropped)
- Fixing HoodieWriteHandle impls to properly handle writer schema and avoid duplication
- Fixing MergeHelper impls to properly handle schema evolution

- * B2. A field has been renamed (treated as delete + add)
- * B3. A field's type has changed to be incompatible with the older type
- *
- * Issue with org.apache.avro.SchemaCompatibility:
- * org.apache.avro.SchemaCompatibility checks schema compatibility between a writer schema (which originally wrote
- * the AVRO record) and a readerSchema (with which we are reading the record). It ONLY guarantees that that each
- * field in the reader record can be populated from the writer record. Hence, if the reader schema is missing a
- * field, it is still compatible with the writer schema.
- *
- * In other words, org.apache.avro.SchemaCompatibility was written to guarantee that we can read the data written
- * earlier. It does not guarantee schema evolution for HUDI (B1 above).
- *
- * Implementation: This function implements specific HUDI specific checks (listed below) and defers the remaining
- * checks to the org.apache.avro.SchemaCompatibility code.
- *
- * Checks:
- * C1. If there is no change in schema: success
- * C2. If a field has been deleted in new schema: failure
- * C3. If a field has been added in new schema: it should have default value specified
- * C4. If a field has been renamed(treated as delete + add): failure
- * C5. If a field type has changed: failure
- *
- * @param oldSchema Older schema to check.
- * @param newSchema Newer schema to check.
- * @return True if the schema validation is successful
- *
- * TODO revisit this method: it's implemented incorrectly as it might be applying different criteria
- * to top-level record and nested record (for ex, if that nested record is contained w/in an array)
