Y Ethan Guo commented on HUDI-8632:
-----------------------------------
Found another issue: HUDI-8896. Right now reading partition columns for
bootstrapped table (bootstrap skeleton + data file) relies on engine-specific
handling, not in the file group reader. So compaction and clustering using the
file group reader to read out records from metadata-only bootstrapped table can
encounter nulls in the partition columns, causing the new base file written to
have nulls in the partition columns.
> Support bootstrap files in file group reader-based compaction

> testMetadataBootstrapMORPartitionedInlineCompactionOn fails with file group
> reader-based compaction (HoodieSparkMergeHandleV2). Currently if the
> compaction plan and operations contain bootstrap files, the compaction goes
> through the old flow using the regular HoodieMergeHandle. We should support
> bootstrap files in file group reader-based compaction in
> HoodieSparkMergeHandleV2.
