Wenchen Fan reassigned SPARK-35378:
-----------------------------------
Assignee: jiaan.geng
> Eagerly execute commands in QueryExecution instead of caller sides
> ------------------------------------------------------------------
>
> Key: SPARK-35378
> URL: https://issues.apache.org/jira/browse/SPARK-35378
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.2.0
> Reporter: jiaan.geng
> Assignee: jiaan.geng
> Priority: Major
>
> Currently, Spark doesn't support LeafRunnableCommand as sub query.
> Because the LeafRunnableCommand always output GenericInternalRow and some
> node(e.g. SortExec, AdaptiveExecutionExec, WholeCodegenExec) will convert
> GenericInternalRow to UnsafeRow. So will causes error as follows:
> {code:java}
> java.lang.ClassCastException
> org.apache.spark.sql.catalyst.expressions.GenericInternalRow cannot be cast
> to org.apache.spark.sql.catalyst.expressions.UnsafeRow
> {code}
