    Description

      In case of crashed task attempts, we may have in rumen logs task attempts with null hostName and finishTime defined to -1

      for example

             {
                "resourceUsageMetrics": {
                  "heapUsage": 0,
                  "physicalMemoryUsage": 0,
                  "virtualMemoryUsage": 0,
                  "cumulativeCpuUsage": 0
                },
                "vmemKbytes": [],
                "physMemKbytes": [],
                "cpuUsages": [],
                "clockSplits": [],
                "location": null,
                "sortFinished": -1,
                "shuffleFinished": -1,
                "spilledRecords": -1,
                "reduceOutputRecords": -1,
                "reduceShuffleBytes": -1,
                "fileBytesRead": -1,
                "hdfsBytesWritten": -1,
                "hdfsBytesRead": -1,
                "hostName": null,
                "finishTime": -1,
                "startTime": 1489619193378,
                "result": null,
                "attemptID": "attempt_1488896259152_410442_r_000015_1",
                "fileBytesWritten": -1,
                "mapInputRecords": -1,
                "mapInputBytes": -1,
                "mapOutputBytes": -1,
                "mapOutputRecords": -1,
                "combineInputRecords": -1,
                "reduceInputGroups": -1,
                "reduceInputRecords": -1
              }
      

      Jackson parser will automatically consider -1 as a java.lang.Integer. However RumenToSLSConverter make the assumption than jackson has deserialize all timstamp as instance of java.lang.Long, resulting in a ClassCastException.

      RumenToSLSConverter also make the assumption that hostName is not null, so we can also have a NullPointerException.
