Review Comment:
If there are value columns (s1, s2, s3), in the first AlignedChunkMetadata,
s2 corresponds to metadata as null, at this time the returned valueChunkList is
(s1, s3). In the subsequent AlignedChunkMetadata, s3 corresponds to metadata as
null, at this time the returned valueChunkList is (s1, s2). Perhaps the two
returns should be (s1, null, s3) (s1, s2, null)
