Date Wed, 02 Aug 2017 12:17:09 GMT
Brahma Reddy Battula created HDFS-12248:
-------------------------------------------

             Summary: SNN will not upload fsimage on IOE and Interrupted exceptions
                 Key: HDFS-12248
                 URL: https://issues.apache.org/jira/browse/HDFS-12248
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: rolling upgrades
            Reporter: Brahma Reddy Battula
            Assignee: Brahma Reddy Battula
            Priority: Critical


Related to  HDFS-9787. When fsimage uploading to ANN, if there is any interrupt or IOE comes
{{isPrimaryCheckPointer}} set to {{false}}.Rollingupgrade tirggered 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.
{code}
      } 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;
{code}
