> Refactor Kafka credential handling into kafka-handler module
> ------------------------------------------------------------
>
> Key: HIVE-27402
> URL: https://issues.apache.org/jira/browse/HIVE-27402
> Project: Hive
> Issue Type: Improvement
> Components: HiveServer2, kafka integration
> Reporter: Stamatis Zampetakis

> Currently the code for handling credentials and authentication for the Kafka
> storage handler is spread across hive-exec
> (https://github.com/apache/hive/blob/7cd3107a76d633ef5fae2ffb8ec16953ac968092/ql/src/java/org/apache/hadoop/hive/ql/exec/tez/DagUtils.java#L302)
> and kafka-handler
> (https://github.com/apache/hive/blob/7cd3107a76d633ef5fae2ffb8ec16953ac968092/kafka-handler/src/java/org/apache/hadoop/hive/kafka/KafkaUtils.java#L71)
> modules. This leads to unexpected dependencies to kafka (e.g., kafka-client)
> in hive-exec module and limits sharing opportunities of credential utilities
> present in KafkaUtil class.
>
> The goal of this refactoring is threefold:
> * centralize Kafka credential handling (in one module) opening the road to
> more code reuse and better encapsulation;
> * remove kafka dependencies (e.g., kafka-client) from hive-exec module;
> * facilitate unit testing and product stability.
