This pr is try to fix the https://github.com/apache/kyuubi/pull/5590 's
problem, but i get some problem, so need someone to help me. The problem desc:
this is the source commt https://github.com/apache/kyuubi/pull/5590
i try to add PaimonDataSourceV2RelationTableExtractor in
TableExtractor to make we can fix the question, but when i add the extractor
and get table info, this is the root call extrcator code
```
case class RuleApplyRowFilter(spark: SparkSession) extends RuleHelper {
override def apply(plan: LogicalPlan): LogicalPlan = {
val newPlan = mapChildren(plan) {
case p: RowFilterMarker => p
case scan if isKnownScan(scan) && scan.resolved =>
val tables = getScanSpec(scan).tables(scan, spark)
tables.headOption.map(applyFilter(scan, _)).getOrElse(scan)
case other => apply(other)
}
newPlan
}
private def applyFilter(
plan: LogicalPlan,
table: Table): LogicalPlan = {
val are = AccessResource(ObjectType.TABLE, table.database.orNull,
table.table, null)
val art = AccessRequest(are, ugi, QUERY, AccessType.SELECT)
val filterExpr = SparkRangerAdminPlugin.getFilterExpr(art).map(parse)
val filtered = filterExpr.foldLeft(plan)((p, expr) => Filter(expr,
RowFilterMarker(p)))
filtered
}
}
```
if we add two exector for the RelationV2 plan, we will get two tables, but
the apply code only use the first table
if the tables is
```
Table(Some(paimon_catalog),None,table1,Some(admin))
Table(Some(paimon_catalog),Some(paimon_ns),table1,Some(admin))
```
the source code will only filter the first table result, is that right?
@bowenliang123 @pan3793 do you know how to solve this?
