I took a look at the accumulo logs on the non-starting servers. They were complaining there was no route to host, and the problem seemed to be with port 9000. I took stab at fixing it by opening said port in iptables. That worked in so much as when I did a jps, I saw a Main process running, so that must be the tserver. However, with the opening of 9000 hadoop datanodes would no longer start. When I closed 9000 (restoring to the first state) hadoop datanodes started as before and the accumulo nodes quit starting. it seems to be one or the other.
Was iptables the wrong thing to do? Is there another way? fwiw, This cluster does not do ssh over port 22.
