> 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}
