    Description

      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.
