- In Spark 3.2, `ALTER TABLE .. RENAME TO PARTITION` throws
`PartitionAlreadyExistsException` instead of `AnalysisException` for tables
from Hive external when the target partition already exists.
+ - In Spark 3.2, script transform default `FIELD DELIMIT` is `\u0001` for no
serde mode. In Spark 3.1 or earlier, the default `FIELD DELIMIT` is `\t`.
Review comment:
Do we need backquote? Maybe ``` `FIELD DELIMIT` ``` -> `FIELD DELIMIT`?
