I tried to figure it out because i saw 2 types of options to configure the "wsrep_cluster_address", is there a difference in configuring the "wsrep_cluster_address" with a comma at the end like so:
wsrep_cluster_address="gcomm://192.168.56.3,192.168.56.4,192.168.56.5,"
and without:
wsrep_cluster_address="gcomm://192.168.56.3,192.168.56.4,192.168.56.5"
From what I see from here, there is no difference between having a comma and not. it will finally use connect
to connect to them.
