> SNNs stop uploading FSImage to ANN once isPrimaryCheckPointer become false.
> Here is the logic to check if upload FSImage or not.
> In StandbyCheckpointer.java
> boolean sendRequest = isPrimaryCheckPointer || secsSinceLast >=
> checkpointConf.getQuietPeriod();
> doCheckpoint(sendRequest);
> The sendRequest is always false if isPrimaryCheckPointer is false giving
> secsSinceLast (~checkpointPeriod) >= checkpointConf.getQuietPeriod()
> (checkpointPeriod * this.quietMultiplier(default value 1.5)) always returns
> false.
