ListenUDP Fault tolerance

[#1]

Hi all, I have built an Apache nifi cluster consisting of 5 nodes and a separate zookeeper server. After that I login to webui and use the ListenUDP processor. This processor opens for example 50000 port on all nodes and it can receive information on any node. For example I will send information to host1:50000, then it should distribute the information on all nodes (host2, host3, host4, host5). It does all this and everything works, but I have two questions.
1) Does host1 participate in sending logs further down the processors or does it just receive and distribute?
2) The Nifi cluster is called fault tolerant, but what if host1 becomes unavailable? Essentially it will not be able to receive information and distribute it to nodes. Is there any solution for this? So that when host1 goes down, the information can be transferred to host2?
