Description:

executor may execute multi tasks concurrently, ExecMapper static state updated
by one task would influence the logic of another task, which may lead to
unpredictable result. To reproduce, execute
{code:sql}
SELECT COUNT(*) FROM TEST TABLESAMPLE(1 ROWS) s
{code},
TEST should be a table with several blocks source data.
