Yes, you should see a tserver running on every node.

Assuming you are starting everything with the accumulo "start-all.sh"
script, you will have to add your other nodes to the conf/slaves file.

If you have already done that, there may be something wrong on the other
hosts (missing files, permissions, ssh keys, etc).

Make sure the accumulo directories sync'd out to every node. Check to make
sure log directories exist and are writable.  If they are there, go to one
of those nodes and check for tserver*.out and tserver*.err files, which
contain the stdout and stderr when the server is started.  Any local issues
will be in those files.

If the tservers manage to start running, and experience an error, you may
see it on the monitor pages, which saves you the trouble of ssh'ing to the
machine and looking in local logs.
