方法详细资料

getClassLoader

ClassLoader getClassLoader()

The class loader for user defined code.

getExecutionParallelism

int getExecutionParallelism()

The actual parallelism this vertex will be run with. In contrast, the JobVertex.getParallelism() is the original parallelism set when creating the JobGraph and might be updated e.g. by the AdaptiveScheduler.

getFinishedAttempt

int getFinishedAttempt(int subtaskIndex)

Get the finished attempt number of subtask.

参数:

subtaskIndex - the subtask index.

返回:

the finished attempt.

抛出:

IllegalArgumentException - Thrown, if subtaskIndex is invalid.
