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.
