Dongjoon Hyun updated SPARK-29957:
----------------------------------
Parent: SPARK-29194
Issue Type: Sub-task (was: Improvement)
> Reset MiniKDC's default enctypes to fit jdk8/jdk11
> --------------------------------------------------
>
> Key: SPARK-29957
> URL: https://issues.apache.org/jira/browse/SPARK-29957
> Project: Spark
> Issue Type: Sub-task
> Components: Tests
> Affects Versions: 3.0.0
> Reporter: angerszhu
> Assignee: angerszhu
> Priority: Major
> Fix For: 3.0.0
>
>
> Since MiniKdc version lower than hadoop-3.0 can't work well in jdk11.
> New encryption types of es128-cts-hmac-sha256-128 and
> aes256-cts-hmac-sha384-192 (for Kerberos 5) enabled by default were added in
> Java 11, while version of MiniKdc under 3.0.0 used by Spark does not support
> these encryption types and does not work well when these encryption types are
> enabled, which results in the authentication failure.
> -----
> Hadoop jira: https://issues.apache.org/jira/browse/HADOOP-12911
> In this jira, the author said to replace origin Apache Directory project
> which is not maintained (but not said it won't work well in jdk11) to Apache
> Kerby which is java binding(fit java version).
> And in Flink: apache/flink#9622
> Author show the reason why hadoop-2.7.2's MminiKdc failed with jdk11.
> Because new encryption types of es128-cts-hmac-sha256-128 and
> aes256-cts-hmac-sha384-192 (for Kerberos 5) enabled by default were added in
> Java 11.
> Spark with hadoop-2.7's MiniKdcdoes not support these encryption types and
> does not work well when these encryption types are enabled, which results in
> the authentication failure.
> And when I test hadoop-2.7.2's minikdc in local, the kerberos 's debug error
> message is read message stream failed, message can't match.
