>                 Key: SPARK-25886
>                 URL: https://issues.apache.org/jira/browse/SPARK-25886
>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 3.0.0
>            Reporter: Gengliang Wang
>            Priority: Minor
>
> Currently in `FailureSafeParser` and `from_avro`, the exception is created with such code
> ```
>   throw new SparkException("Malformed records are detected in record parsing. " +
>     s"Parse Mode: ${FailFastMode.name}.", e.cause)
> ```
> 1. The cause part should be `e` instead of `e.cause`
> 2. If `e` contains non-null message, it should be shown, e.g. 
> ```com.fasterxml.jackson.core.JsonParseException: Unexpected character ('1' (code 49)): was expecting a colon to separate field name and value
>  at [Source: (InputStreamReader); line: 1, column: 7]
> ```
> 3.Kindly show hint for trying PERMISSIVE in error message.
