{code:java}
for (; i < uploads.size(); i++) {
Future<TransferFsImage.TransferResult> upload = uploads.get(i);
try {
// TODO should there be some smarts here about retries nodes that are not
the active NN?
if (upload.get() == TransferFsImage.TransferResult.SUCCESS) {
success = true;
//avoid getting the rest of the results - we don't care since we had a
successful upload
break;
}
} catch (ExecutionException e) {
ioe = new IOException("Exception during image upload", e);
break;
} catch (InterruptedException e) {
ie = e;
break;
}
}
if (ie == null && ioe == null) {
//Update only when response from remote about success or
lastUploadTime = monotonicNow();
// we are primary if we successfully updated the ANN
this.isPrimaryCheckPointer = success;
}
{code}
If `upload.get`occure error, the code `this.isPrimaryCheckPointer = success`
can't be executed.

> {code:java}
> boolean sendRequest = isPrimaryCheckPointer
> || secsSinceLastUpload >= checkpointConf.getQuietPeriod();
> doCheckpoint(sendRequest);
> {code}
> If sendRequest is true, SNN will upload fsimage. But isPrimaryCheckPointer
> always is true,
> {code:java}
> if (ie == null && ioe == null) {
> //Update only when response from remote about success or
> lastUploadTime = monotonicNow();
> // we are primary if we successfully updated the ANN
> this.isPrimaryCheckPointer = success;
> }
> {code}
> isPrimaryCheckPointer should be outside the if condition.
> If the ANN update was not successful, then isPrimaryCheckPointer should be
> set to false.
