> Key: SPARK-33826
> URL: https://issues.apache.org/jira/browse/SPARK-33826
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.3.2, 3.0.0
> Reporter: Zhang Jianguo
> Priority: Minor
>
> *Arch:* Hive on Spark.
>
> *Version:* Spark 2.3.2
>
> *Conf:*
> Enable user impersonation
> hive.server2.enable.doAs=true
>
> *Scenario:*
> Thriftserver is running with loginUser A, and Task run as User A too.
> Client execute SQL with user B
>
> Data generated by sql "insert into TABLE \[tbl\] select XXX form XXXX." is written to HDFS on executor, executor doesn't know B.
>
> *{color:#de350b}So the user file written to HDFS will be user A which should be B.{color}*
>
> I also check the inplementation of Spark 3.0.0, It could have the same issue.
