### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) ### Search before asking - [X] I have searched in the [issues](https://github.com/apache/kyuubi/issues?q=is%3Aissue) and found no similar issues. ### Describe the bug Hi, we're using your `spark-authz` lib which started crashing for some workflows after upgrading 1.6.1 -> 1.7.1 This only happens when joining a table that contains masked columns even though they're not used in the join condition. ``` Exception in thread "main" java.lang.ClassCastException: class org.apache.kyuubi.plugin.spark.authz.ranger.datamasking.DataMaskingStage1Marker cannot be cast to class org.apache.spark.sql.catalyst.plans.logical.Join (org.apache.kyuubi.plugin.spark.authz.ranger.datamasking.DataMaskingStage1Marker and org.apache.spark.sql.catalyst.plans.logical.Join are in unnamed module of loader 'app') at org.apache.spark.sql.Dataset.resolveSelfJoinCondition(Dataset.scala:1069) at org.apache.spark.sql.Dataset.join(Dataset.scala:1117) [..] our code ``` This should be enough to reproduce it: ``` val df0 = sqlContext.table("table_with_masked_col") // only col2 is masked which is not used .select($"col0", $"col1") df0.as("a") .join( right = df0.as("b"), joinExprs = $"a.col0" === $"b.col0" && $"a.col1" === $"b.col1", joinType = "left_outer") // crashes ``` We had to downgrade to 1.6.1 where this doesn't happen. ### Affects Version(s) 1.7.1 ### Kyuubi Server Log Output _No response_ ### Kyuubi Engine Log Output _No response_ ### Kyuubi Server Configurations _No response_ ### Kyuubi Engine Configurations _No response_ ### Additional context _No response_ ### Are you willing to submit PR? - [ ] Yes.
