-------------------------------
Summary: KStreamReduce and KTableReduce should not pass nulls to
Deserializers
Key: KAFKA-3836
URL: https://issues.apache.org/jira/browse/KAFKA-3836
Project: Kafka
Issue Type: Improvement
Components: streams
Affects Versions: 0.10.0.0
Reporter: Avi Flax
Assignee: Guozhang Wang
Priority: Trivial
As per [this
discussion|http://mail-archives.apache.org/mod_mbox/kafka-users/201606.mbox/%3ccahwhrru29jw4jgvhsijwbvlzb3bc6qz6pbh9tqcfbcorjk4...@mail.gmail.com%3e]
these classes currently pass null values along to Deserializers, so those
Deserializers need to handle null inputs and pass them through without
throwing. It would be better for these classes to simply not call the
Deserializers in this case; this would reduce the burden of implementers of
{{Deserializer}}.
