             Summary: LatestCompletedCheckpointExternalPathGauge should check if external path is exist
                 Key: FLINK-7675
                 URL: https://issues.apache.org/jira/browse/FLINK-7675
             Project: Flink
          Issue Type: Bug
          Components: Metrics
    Affects Versions: 1.4.0, 1.3.3
            Reporter: Wei-Che Wei


For internal checkpoint, {{CompletedCheckpointStats.getExternalPath()}} could be {{null}}.
This will leads to {{LatestCompletedCheckpointExternalPathGauge}} to return {{null}} value to {{MetricDumpSerialization}}, which will throw {{NullPointerException}} when serialize {{Gauge}}.
