> {{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}
