Description

A recent change (KUDU-861) added the ability to alter column defaults. However, after altering a default, accessing the table's metadata does not reflect the new default in the ColumnSchema.

The new default is applied correctly to newly inserted rows, and other attributes that can be altered from that patch, ENCODING, COMPRESSION, and BLOCK_SIZE, show up in the metadata correctly.

A small repro is attached.
