Review Comment:
@yihua, you are right, it could lead to an empty result from queries with
filters, when `TimestampKeyGenerator` is used as values for partition column.
But the problem is with `prunedPartitionsAndFilteredFileSlices` in
`HoodieFileIndex::listFiles`. Null partition column values lead to
`PartitionDirectory`s with null values due to used
`InternalRow.fromSeq(partitionOpt.get.values)`.
I opened a separate related task: HUDI-7952, and will search for proper
fixing.
