Allison Wang updated SPARK-45765:
---------------------------------
Description:
Currently, the error message is super confusing when a user tries to load
multiple paths incorrectly.
For example, `spark.read.format("json").load("p1", "p2")` will have this error:
An error occurred while calling o36.load.
: org.apache.spark.SparkClassNotFoundException: [DATA_SOURCE_NOT_FOUND] Failed
to find the data source: p2. Please find packages at
`[https://spark.apache.org/third-party-projects.html]`. SQLSTATE: 42K02
This can be confusing but it's valid error message, as "p2" will be considered
as the `format` field of the load() method.

We should fix this.
