Hequn Cheng updated FLINK-7410:
-------------------------------
    Description:=20
*Motivation*

Operator names setted in table-api are used by visualization and logging, i=
t is import to make these names simple and readable. Currently, UserDefined=
Function=E2=80=99s name contains class CanonicalName and md5 value making t=
he name too long and unfriendly to users.=20

As shown in the following example,=20
{quote}
select: (a, b, c, org$apache$flink$table$expressions$utils$RichFunc1$281f7e=
61ec5d8da894f5783e2e17a4f5(a) AS _c3, org$apache$flink$table$expressions$ut=
ils$RichFunc2$fb99077e565685ebc5f48b27edc14d98(c) AS _c4)
{quote}

*Changes:*
=09=09=09
Use {{toString}} method to display operator names for UserDefinedFunction. =
The method will return class name by default. Users can also override the m=
ethod to return whatever he wants.

What do you think [~fhueske] ?
