> Check startTime in SparkTask to make sure startTime is not less than
> submitTime. We saw a corner case when the sparkTask is finished in less than
> 1 second, the startTime may not be set because RemoteSparkJobMonitor will
> sleep for 1 second then check the state, in this case, right after sleep for
> one second, the spark job is already completed. one example query with 3
> spark tasks, the second one finished quickly for around 1 second:
> {code}
> SparkTask1:
> "finishTime":1484638391978
> "submitTime":1484638385933
> "startTime": 1484638386973
> SparkTask2:
> "finishTime":1484638393019
> "submitTime":1484638391979
> "startTime": 1484638386973
> SparkTask3:
> "finishTime":1484638432123
> "submitTime":1484638393020
> "startTime": 1484638394057
