[jira] [Created] (KUDU-3142) Deprecate kudu-mapreduce integration

Grant Henke created KUDU-3142:
---------------------------------

             Summary: Deprecate kudu-mapreduce integration
                 Key: KUDU-3142
                 URL: https://issues.apache.org/jira/browse/KUDU-3142
             Project: Kudu
          Issue Type: Task
    Affects Versions: 1.12.0
            Reporter: Grant Henke
            Assignee: Grant Henke


The kudu-mapreduce integration has not been improved in a couple of years even though there are known outstanding issues and feature gaps. Additionally similar functionality and capabilities now exist via Spark, Hive, Impala, and NiFi integrations. We should document the deprecation of the kudu-mapreduce integration to notify users and so that we can remove it if maintenance becomes an issue.

Even if eventually removed, users can still use the jars published in older versions as needed.
Additionally if a Hadoop InputFormat and OutputFormat is required, a much more modern and maintained version is available in the Apache Hive project: https://github.com/apache/hive/tree/master/kudu-handler/src/java/org/apache/hadoop/hive/kudu
