Description

Related to HDFS-9787. When fsimage uploading to ANN, if there is any interrupt or IOE comes isPrimaryCheckPointer set to false.Rollingupgrade triggered same time then It does the checkpoint without sending the fsimage since sendRequest will be false.
So,here rollback image will not sent to ANN.

      } catch (ExecutionException e) {
        ioe = new IOException("Exception during image upload: " + e.getMessage(),
            e.getCause());
        break;
      } catch (InterruptedException e) {
        ie = e;
        break;
      }
    }
    lastUploadTime = monotonicNow();

    // we are primary if we successfully updated the ANN
    this.isPrimaryCheckPointer = success;
