When an execution node fails, the jobs running on the node fail and require a restart when the node is restored.
当某个执行节点出现故障时，在那个节点上运行的作业会失败，需要在节点恢复后重新开始运行。
This ensures that the state can be recovered from either the scheduling node or the execution node in event of failure.
这样就确保了当调度节点或者执行节点出现故障时那些状态可以恢复。
The establishment of a backup execution node would immediately provide the capability to restart the job in a more timely fashion.
备份执行节点的建立，将直接提供在更短时间内重新开始运行作业的能力。
Neither the scheduling node nor the execution node discard the job information until it is passed on to, and accepted by, the other node.
调度节点和执行节点都不会丢弃作业的信息，直到它被传递到其他节点并被接受。
The scheduling node and the execution node use a protocol that ensures that the state information is kept on disk by at least one of them.
调度节点和执行节点通过一个协议来确保至少它们其中一个要在磁盘上保持那些状态信息。
When you apply load balancing during runtime, it is called dynamic load balancing - this can be realized both in a direct or iterative manner according to the execution node selection.
在运行时应用负载平衡时，它被称之为动态负载平衡—这可以根据执行节点选择直接实现或以迭代的方式实现。
