Review Comment:
   But sometimes, some Java exceptions information can help users locate the 
specific problem. For example, the exception of 
url_decode('http%3A%2F%2spark.apache.org') will indicate that the error is "2s".
   
   > Illegal hex characters in escape (%) pattern - For input string: "2s"
   
   This is beneficial for users to quickly locate, just like the parsing error 
of sql parse, what do you think?
