Review Comment:
As I see, this function is called within `runSegmentLevelValidation`. Under
normal circumstances, this call shouldn't fetch all the segment ZK metadata as
not many segments should be in `ERROR`.
Moreover, segment level validations run at a reduced frequency as they fetch
segment ZK metadata for all the segments e.g. missing download url.
These segment level validations don't impact the query or ingestion. Other
things done by RealtimeSegmentValidationManager are ensuring that the ingestion
works fine even in case of commit protocol failure.
I feel re-ingestion is `critical` as this will impact queries (`partial
results` in case of `single stage` query engine and `complete failure` in case
of `multi-stage` query engine) and hence should not be under segment level
validations.
