Review comment:
I couldn't find a way to add `enable validate norely` to any constraint.
I think `validate` is not supported yet, because I keep getting
`org.apache.hadoop.hive.ql.parse.SemanticException: Invalid Foreign Key syntax
VALIDATE feature not supported yet. Please use NOVALIDATE instead.`
Also, I consulted the language manual -
https://cwiki.apache.org/confluence/display/hive/languagemanual+ddl#LanguageManualDDL-CreateTableCreate/Drop/TruncateTable
- where I couldn't find an example with `validate`.
Do let me know if you have a suggestion!
