Description
HA mode,the "ipc.client.connect.max.retries.on.timeouts" and "ipc.client.connect.max.retries" is set zero,but if met active NN's ip changed,it will detect the change,but won't reconnect because exceed the max retry times,after do 15 times failover and then throw connection or standby exception.
maybe if found the address is changed,should reconnect immediately no matter the retry times limit.
log is below:
