Was wondering if RC2 is expected to release soon? Any chance that could be added to
branch-2.4 as well for 2.4.5 release? Especially since 2.4.x introduced the

Hi, All.

RC2 was scheduled on Today and all RC1 feedbacks seems to be addressed.
However, I'm waiting for another on-going correctness PR.
    [SPARK-29701][SQL] Correct behaviours of group analytical queries when
empty input given

Unlike the other correctness issues (I sent previsouly), this one is active
enough to make RC2 fail. As we know, Spark 2.4.5 RC1 vote failed because
the correctness patch landed on `master` branch during the RC1 vote period
and there was official requests for backporting.
    [SPARK-29708][SQL][2.4] Correct aggregated values when grouping sets
are duplicated

It's risk to start RC2 without considering it because VOTE is also
consuming the community resources.

BTW, if there is another on-going notable PR for 2.4.5 RC1, please reply to
