>
> In #RATIS-2148, the issue of receiving the last snapshot file without
> considering the possibility of intermediate blocks failing was fixed, which
> resulted in the incorrect triggering of loadStateMachine.
> Some issues were missed in #RATIS-2148:
>
> For example, Leader L will send the following data to Follower F in the form
> of a snapshot: data [a, b, c,..., z].
> L will split the data into 0: [a, b, c, d], 1: [e, f, g, h],...
> F already contains data [a, b, c, d, e].
> F will reply with ALREADY_INSTALL after receiving data-0 and will not update
> nextChunkIndex.
>
> This will result in failure to receive subsequent data_chunk correctly.
