Summary: Fix Flaky test RaftAsyncTests#StaleReadAsync &
RaftAsyncTests#testStateMachineMetrics
Key: RATIS-2294
URL: https://issues.apache.org/jira/browse/RATIS-2294
Project: Ratis
Issue Type: Improvement
Reporter: Shilun Fan
Assignee: Shilun Fan
I'm currently follow up on RATIS-2251, and test results indicate that we have
some flaky tests. I'm working on identifying and resolving the root causes.
Specifically, I found that testStaleReadAsync and testStateMachineMetrics are
failing because the client doesn't know the correct leaderId, which leads to
request failures.
In async mode, if the leaderId is not explicitly specified, the default used in
tests is s0. However, during actual test execution with three peers (s0, s1,
and s2), any of them can become the leader. Therefore, we need to explicitly
set the correct leaderId for the client to ensure reliable communication.
