> From the actual situation, the probability of this happening is very low.
> It can only be caused by the master-slave fail-hover of YARN and the wrong
> Epoch parameter configuration.
> We will try to be compatible with this situation and let the Application run
> as much as possible, using the following measures:
> 1. Select a node whose heartbeat does not time out for allocation, and at the
> same time require the node to be in the RUNNING state.
> 2. If the heartbeat of both RMs does not time out, and both are in the
> RUNNING state, select the previously allocated RM for Container processing.
