[jira] [Commented] (SPARK-31961) Add a class in spark with all Kafka configuration key available as string

["Jungtaek Lim (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-31961?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17132707#comment-17132707 ] 

Jungtaek Lim commented on SPARK-31961:
--------------------------------------

Don't you think the constant should be available in Kafka instead of Spark? Spark should try to avoid being tie to the specific version of Kafka in codebase. If Kafka provides it, what you need is just add "kafka." as prefix.
