But it does not indicate the HashJoin must have a RuntimeFilterDef. There's some preconditions defined at the `RuntimeFilterManager` such as Left join is not allowed to use a BF to filter data. So we can't use `Preconditions.checkState(runtimeFilterDef != null)`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
