Problem:
When window function in aggregation function, executor would report an error like: Required field 'node_type' was not present!
Example:
SELECT SUM(MAX(c1) OVER (PARTITION BY c2, c3)) FROM test_window_in_agg;
Reason:
When analyze aggregate, analytic expr (window function carrior when analyze) transfered to slot and loss message. So when
serialize to thrift package, TExpr can not determine node_type of analytic expr.
Solved:
We do not support aggregate(window function) yet. So we report an error when analyze.
