Tim Armstrong updated IMPALA-9019: ---------------------------------- Description: It looks like runtime filters do not get delivered properly. E.g. if I run TPC-H Q 9 with mt_dop=4 and runtime_filter_wait_time_ms=999999, the query appears to get stuck. This causes TPC-H performance to be significantly worse for some queries. Strangely, I can only reproduce this on TPC-H scale factor 3, not the smaller scale factor. was: It looks like runtime filters do not get delivered properly.
