> *What's the problem ?*
> !screenshot-1.png!
> *What's the reason ?*
> I think the author of following code want to try 10 seconds until
> followerState.getLastAppliedIndex() >= leaderLastIndex, but actually
> JavaUtils.attemptRepeatedly will not retry unless the statement throw
> exception as the image shows.
> {code:java}
> // make sure the restarted follower can catchup
> final ServerState followerState =
> cluster.getRaftServerImpl(followerId).getState();
> JavaUtils.attemptRepeatedly(() -> followerState.getLastAppliedIndex() >=
> leaderLastIndex,
> 10, ONE_SECOND, "follower catchup", LOG);
> {code}
> !screenshot-2.png!
> *How to fix ?*
> I fix all the error use of JavaUtils.attemptRepeatedly to check boolean
> condition.
