Jason Gustafson resolved KAFKA-10800.
-------------------------------------
Resolution: Fixed
> Validate the snapshot id when the state machine creates a snapshot
> ------------------------------------------------------------------
>
> Key: KAFKA-10800
> URL: https://issues.apache.org/jira/browse/KAFKA-10800
> Project: Kafka
> Issue Type: Sub-task
> Components: replication
> Reporter: Jose Armando Garcia Sancio
> Assignee: Haoran Xuan
> Priority: Major
>
> When the state machine attempts to create a snapshot writer we should
> validate that the following is true:
> # The end offset of the snapshot is less than or equal to the high-watermark.
> # The epoch of the snapshot is less than or equal to the quorum epoch.
> # The end offset and epoch of the snapshot is valid based on the leader
> epoch cache.
> Note that this validation should not be performed when the raft client
> creates the snapshot writer because in that case the local log is out of date
> and the follower should trust the snapshot id sent by the partition leader.
