Re: Facing issue in RichSinkFunction

[Hequn Cheng <ch...@gmail.com>]

Hi Amol,

The implementation of the RichSinkFunction probably contains a field that
is not serializable. To avoid serializable exception, you can:
1. Marking the field as transient. This makes the serialization mechanism
skip the field.
2. If the field is part of the object's persistent state, the type of the
field must implement Serializable.

Furthermore, you can remove some fields to locate the problem fields.

Best, Hequn
