> 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}
> scala> sql("create table t(a int)").show
>  scala> sql("desc formatted t").show(false)
>  ...
