text: nifi.cluster.load.balance.port
  Specifies the port to listen on for incoming connections for load balancing data across the cluster. The default value is 6342.
  nifi.cluster.load.balance.host
  Specifies the hostname to listen on for incoming connections for load balancing data across the cluster. If not specified, will default to the value used by the nifi.cluster.node.address property.
  nifi.cluster.load.balance.connections.per.node
  The maximum number of connections to create between this node and each other node in the cluster. For example, if there are 5 nodes in the cluster and this value is set to 4, there will be up to 20 socket connections established for load-balancing purposes (5 x 4 = 20). The default value is 1.
  nifi.cluster.load.balance.max.thread.count
  The maximum number of threads to use for transferring data from this node to other nodes in the cluster. While a given thread can only write to a single socket at a time, a single thread is capable of servicing multiple connections simultaneously because a given connection may not be available for reading/writing at any given time. The default value is 8-i.e., up to 8 threads will be responsible for transferring data to other nodes, regardless of how many nodes are in the cluster.
  NOTE: Increasing this value will allow additional threads to be used for communicating with other nodes in the cluster and writing the data to the Content and FlowFile Repositories. However, if this property is set to a value greater than the number of nodes in the cluster multiplied by the number of connections per node (nifi.cluster.load.balance.connections.per.node), then no further benefit will be gained and resources will be wasted.
  nifi.cluster.load.balance.comms.timeout
  When communicating with another node, if this amount of time elapses without making any progress when reading from or writing to a socket, then a TimeoutException will be thrown. This will then result in the data either being retried or sent to another node in the cluster, depending on the configured Load Balancing Strategy. The default value is 30 sec.
