> ProjectionPushDownRule incorrectly rewrite the output schema of StoreTableNode

> Key: TAJO-463
> URL: https://issues.apache.org/jira/browse/TAJO-463
> Project: Tajo
> Issue Type: Bug
> Components: planner/optimizer
> Reporter: Min Zhou
> Assignee: Hyunsik Choi
>
> When I was implementing CTAS on partitioned table, I ran into a schema
> problem if my target column names are different from select clause's output
> schema.
>
> {noformat}
> create table tbl (col1 int4, col2 int4, null_col int4) partition by
> column(key float8) as select l_orderkey as col1, l_partkey as col2,
> l_quantity as key from lineitem
> {noformat}
> After debugging, I found ProjectionPushDownRule would replace
> StoreTableNode's output schema with its child output schema.
> {noformat}
> @Override
> public LogicalNode visitStoreTable(PushDownContext context, LogicalPlan
> plan, StoreTableNode node,
> Stack<LogicalNode> stack) throws
> PlanningException {
> return pushDownCommonPost(context, node, stack);
> }
> private LogicalNode pushDownCommonPost(PushDownContext context, UnaryNode
> node, Stack<LogicalNode> stack)
> throws PlanningException {
> stack.push(node);
> LogicalNode child = visitChild(context, context.plan, node.getChild(),
> stack);
> stack.pop();
> node.setInSchema(child.getOutSchema());
> node.setOutSchema(child.getOutSchema()); // THIS LINE WILL REWRITE THE
> SCHEMA!
> if (node instanceof Projectable) {
> pushDownProjectablePost(context, node, isTopmostProjectable(stack));
> }
> return node;
> }
> {noformat}
