+++ This bug was initially created as a clone of Bug #1861683 +++

Description of problem:
When deploy a pod with custom scheduler can't show the custom scheduler name correctly on the Event

Version-Release number of selected component (if applicable):
4.6.0-0.nightly-2020-07-25-091217

How reproducible:
always

Steps to Reproduce:
1) Deploy custom scheduler named "my-scheduler"
2) Create a pod to use the custom scheduler with yaml :
[root@dhcp-140-138 ~]# cat /tmp/annotation-second-scheduler.yaml 
apiVersion: v1
kind: Pod
metadata:
  name: annotation-second-scheduler
  labels:
    name: multischeduler-example
spec:
  schedulerName: my-scheduler
  containers:
  - name: pod-with-no-annotation-container
    image: "quay.io/openshifttest/pause@sha256:b31bfb4d0213f254d361e0079deaaebefa4f82ba7aa76ef82e90b4935ad5b105"
3) Check the name of the scheduler for the pod

Actual results:
3) Show nothing for the scheduler name , and show <unknown> for the Age.

[root@dhcp-140-138 ~]# oc describe po/annotation-second-scheduler
Name:         annotation-second-scheduler
Namespace:    zhouyt2
Events:
  Type    Reason          Age        From                                                 Message
  ----    ------          ----       ----                                                 -------
  Normal  Scheduled       <unknown>                                                       Successfully assigned zhouyt2/annotation-second-scheduler to ip-xxx

Expected results:
3. Show the scheduler name and Age  correctly

Age is not properly set since FirstTimestamp, resp. LastTimestamp fields are not set due to the fact both fields are deprecated with 1.19 (core event type is replaced with event v1 type) and not properly set in 1.18 or less (core event type is replaced with event v1beta1 type). The way the Age is computed will need to change eventually.

In 4.5 or less the solution is to set both DeprecatedLastTimestamp and DeprecatedFirstTimestamp when issuing v1beta1 event. Which, when converted to the core event type gets translated into LastTimestamp and FirstTimestamp.
In 4.6 different approach is required since both fields are no longer set.

--- Additional comment from Jan Chaloupka on 2020-08-04 11:55:54 UTC ---

From field is read from core event's Source field which is deprecated as well. There's a DeprecatedSource field which can not be set in 1.19 as well. New v1 event has a ReportingController field which can be used instead.

--- Additional comment from Jan Chaloupka on 2020-08-04 16:05:13 UTC ---

In 4.6 the Age column is properly set through https://github.com/openshift/oc/commit/bda51beaf869421bba0ce4eb32602d3af05497f2#diff-03ff3bfb36119113ef012cfe8771c5c6R3872-R3874 (oc rebase to 1.19.0-rc.1) so no need to address that anymore (tested locally).

@jan chaloupka, i see that not only custom-scheduler but cannot see default-scheduler name as well. See the describe below. I see the bug is already in POST state, hopefully the PR fixes this issue as well. could you please confirm ?

Yes, it does.

Thanks !!

Backporting https://github.com/kubernetes/kubernetes/pull/90227 to 1.18 as a replacement for https://github.com/kubernetes/kubernetes/pull/93663 (which got closed as not sufficient solution).

--- Additional comment from Jan Chaloupka on 2020-08-26 12:34:37 UTC ---

All the fixes are merged in upstream master branch. I will wait until 1.19 GA is rebased and underlying BZ is in MODIFIED state.
