Labels: pull-request-available (was: )
> Missing case for RelationTimeTravel in CheckAnalysis
> ----------------------------------------------------
>
> Key: SPARK-45383
> URL: https://issues.apache.org/jira/browse/SPARK-45383
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.5.0
> Reporter: Ryan Johnson
> Priority: Major
> Labels: pull-request-available
>
> {{CheckAnalysis.checkAnalysis0}} lacks a case for {{{}RelationTimeTravel{}}},
> and since the latter is (intentionally) an {{UnresolvedLeafNode}} rather than
> a {{{}UnaryNode{}}}, the existing checks do not traverse it.
> Result: Attempting time travel over a non-existing table produces a spark
> internal error from the [default
> case|https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/CheckAnalysis.scala#L818],
> rather than the expected {{{}AnalysisException{}}}:
> {code:java}
> [info] Cause: org.apache.spark.SparkException: [INTERNAL_ERROR] Found the
> unresolved operator: 'RelationTimeTravel 'UnresolvedRelation [not_exists],
> [], false, 0
> [info] at
> org.apache.spark.SparkException$.internalError(SparkException.scala:77)
> [info] at
> org.apache.spark.sql.catalyst.analysis.CheckAnalysis.$anonfun$checkAnalysis0$54(CheckAnalysis.scala:753)
> {code}
> Fix should be simple enough:
> {code:java}
> case tt: RelationTimeTravel =>
> checkAnalysis0(tt.table) {code}
