Kent Yao commented on RANGER-2128:
----------------------------------
Hi [~bosco] You can try Spark 2.3.1, because this change
https://github.com/apache/spark/blob/branch-2.3/sql/hive/src/main/scala/org/apache/spark/sql/hive/client/HiveClientImpl.scala#L129
ensures the SessionState that contains the thrift user body will be reused.
But there is still a problem that the hive metastore client which contains the
ugi for authorization is shared among SparkSession s inside Spark Thrift Sever.
We can not reuse it for different users. We may need to manage a <user,
SessionState> map to do privileges checking, which may left "show tables" /
"show databases" ... statements unchecked and cause plenty of connections to
the metastore server.
