----------------------------
Summary: Regarding the follow-up patch issue of RATIS-2148
Key: RATIS-2166
URL: https://issues.apache.org/jira/browse/RATIS-2166
Project: Ratis
Issue Type: Bug
Reporter: yuuka
In Create Issue - ASF JIRA (apache.org) 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 #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 has 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.
