> In the first version of speculative execution, an
> ExecutionTimeBasedSlowTaskDetector will be used to detect slow tasks. For
> ExecutionTimeBasedSlowTaskDetector, if a task's execution time is much longer
> than that of most tasks of the same JobVertex, the task will be identified as
> slow. More specifically, it will compute an execution time baseline for each
> JobVertex. Tasks which execute longer than or equals to the baseline will be
> identified as slow tasks.
