> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.3.0, 2.3.1, 2.3.2, 2.3.3, 2.4.0
> Reporter: hong dongdong
> Priority: Major
>
> In kerberos cluster, when use spark-sql or beeline to create table, the
> owner will be whole info of principal. the _issue_ was fixed in SPARK-19970
> and modify by SPARK-22846, so it occur again. It will causes some problems
> when using role., and this time should resolved two issues together.
> Use org.apache.hadoop.hive.shims.Utils.getUGI directly to get
> ugi.getShortUserName
> instead of use conf.getUser which return principal info.
> Code change
> {code:java}
> private val userName: String = try {
> val ugi = HiveUtils.getUGI
> ugi.getShortUserName
> } catch {
> case e: LoginException => throw new IOException(e)
> }
> {code}
> Berfore
> {code}
