Inigo Goiri commented on HDFS-9787:
-----------------------------------
Now that I see this, can it be the problem that we do:
{code}
// Reset checkpoint time so that we don't always checkpoint
// on startup.
lastCheckpointTime = monotonicNow();
{code}
And then:
{code}
lastCheckpointTime = now;
{code}
We'll do the test in our cluster anyway.
> SNNs stop uploading FSImage to ANN once isPrimaryCheckPointer changed to false.

> 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.
