> Components: Table API & SQL
> Affects Versions: 1.4.0
> Reporter: Hequn Cheng
> Assignee: Hequn Cheng

> *Motivation*
> Operator names setted in table-api are used by visualization and logging, it
> is import to make these names simple and readable. Currently,
> UserDefinedFunction’s name contains class CanonicalName and md5 value making
> the name too long and unfriendly to users.
> As shown in the following example,
> {quote}
> select: (a, b, c,
> org$apache$flink$table$expressions$utils$RichFunc1$281f7e61ec5d8da894f5783e2e17a4f5(a)

> *Changes:*

> Use {{toString}} method to display operator names for UserDefinedFunction.
> The method will return class name by default. Users can also override the
> method to return whatever he wants.
