Did you try setting the increased size in the zkCli.sh command (or wherever it gets it environment from?)
The ZK docs indicate that it needs to be set to the same size on all servers and clients. You should be able to use zkCli.sh to at least see what's going on - if that does not work, then it seems unlikely that the master would either. Can you: * list the nodes under /accumulo/[instance id]/fate? * use the stat command on each of the nodes - the size is one of the fields. * list nodes under any of the /accumulo/[instance_id/fate/tx-##### * there should be a node named debug - doing a get on that should show the op name.
