Prashant Wason updated HUDI-741:
--------------------------------
Status: Open (was: New)
> Fix Hoodie's schema evolution checks
> ------------------------------------
>
> Key: HUDI-741
> URL: https://issues.apache.org/jira/browse/HUDI-741
> Project: Apache Hudi (incubating)
> Issue Type: Bug
> Reporter: Prashant Wason
> Priority: Minor
> Original Estimate: 120h
> Remaining Estimate: 120h
>
> HUDI requires a Schema to be specified in HoodieWriteConfig and is used by
> the HoodieWriteClient to create the records. The schema is also saved in the
> data files (parquet format) and log files (avro format).
> Since a schema is required each time new data is ingested into a HUDI
> dataset, schema can be evolved over time. But HUDI should ensure that the
> evolved schema is compatible with the older schema.
> HUDI specific validation of schema evolution should ensure that a newer
> schema can be used for the dataset by checking that the data written using
> the old schema can be read using the new schema.
