    If the leaderEpoch of the incoming request is higher than locally cached epoch, make the local replica the follower in the following steps.

    If the leaderEpoch of the incoming request is higher than locally cached epoch, make the local replica the follower in the following steps.

    1. stop any existing fetcher on this partition from the local replica 2. make sure local replica exists and truncate the log to high watermark 3. set the leader and set ISR to empty 4. start a fetcher to the new leader

  41. def makeLeader(controllerId: Int, topic: String, partitionId: Int, leaderIsrAndControllerEpoch: LeaderIsrAndControllerEpoch, correlationId: Int): Boolean

    If the leaderEpoch of the incoming request is higher than locally cached epoch, make the local replica the leader in the following steps.

    If the leaderEpoch of the incoming request is higher than locally cached epoch, make the local replica the leader in the following steps.

    1. stop the existing replica fetcher 2. create replicas in ISR if needed (the ISR expand/shrink logic needs replicas in ISR to be available) 3. reset LogEndOffset for remote replicas (there could be old LogEndOffset from the time when this broker was the leader last time) 4. set the new leader and ISR
