---------------------------------
Summary: Include an example in the JDBC hint option validation
error message
Key: SPARK-58865
URL: https://issues.apache.org/jira/browse/SPARK-58865
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 4.3.0
Reporter: Ganesha S
The JDBC hint option must be wrapped as /*+ ... */. When the value fails this
check, the error describes the required delimiters in words only:
Invalid value `<value>` for option `hint`. It should start with `/*+ ` and end
with ` */`.
The required leading/trailing spaces inside /*+ and */ are easy to miss, and
a prose description is slower to act on than a worked example.
Proposed: add an example to the message:
{code:java}
Invalid value `<value>` for option `hint`.{code}
It should start with `/*+ ` and end with ` */`, for example `/*+ INDEX(t1
id_idx) */`.
Validation behavior is unchanged; only the error text is improved.
