-----------------------------------------
Summary: STORM-2548 on 1.x-branch broke setting key/value
deserializers with the now deprecated setKey/setValue methods
Key: STORM-2756
URL: https://issues.apache.org/jira/browse/STORM-2756
Project: Apache Storm
Issue Type: Bug
Components: storm-kafka-client
Affects Versions: 1.2.0
Reporter: Stig Rohde Døssing
Assignee: Stig Rohde Døssing
When STORM-2548 was backported, the setKey/setValue methods on
KafkaSpoutConfig.Builder were deprecated, and users were directed to use
setProp along with the relevant ConsumerConfig constants for setting
deserializers instead.
As part of this change, the KafkaConsumerFactoryDefault switched from using the
KafkaConsumer(props, keyDes, valDes) constructor to using the
KafkaConsumer(props) constructor. Unfortunately I forgot to update the
KafkaSpoutConfig.Builder constructor properly, so if the user configures the
deserializer via either the Builder constructor parameters or setKey/setValue,
the setting is not put in the kafkaProps map and the deserializer is not used.
