Interesting. What version of Accumulo are you using?

Also, can you jstack your client application, maybe we can get a hint where it's stuck. You could also try increase the Log4j level in your client application for the 'org.apache.accumulo.core' package to DEBUG or TRACE.

Even better, if this is something you can share (making assumptions since it's Vagrant-based), feel free to. I'll try to run your example and poke around myself.

    Each line in the Accumulo "hosts" files (masters, slaves, etc)
    denote a host which the process should be run on, FYI.

    What does netstat show for ports 9999 and 9997? Those are the two
    ports that your client should ever need to talk to for Accumulo, IIRC.

             Mike,

             I suspect if you get rid of the "localhost" line and restart
             Accumulo then you will get services listening on the
        non-loopback
             IPs. Right now you have some of your processes accessible
        outside
             your VM and others only accessible from inside, and you
        probably
             have two tablet servers when you should only have one.

             Cheers,
             Adam

                 It would hang at the first scan or write operation I
        tried. I
                 checked the master port (9999) and it was only listening on
        127.0.0.1:9999 <http://127.0.0.1:9999> <http://127.0.0.1:9999>.
        netstat had two entries
                 for 9997. This is what conf/masters has for my VM:

                 localhost
                 vagrant-ubuntu-vivid-64

                 It's the same with all of the other files (slaves, gc,
        etc.)

                 Any ideas?

                 Thanks,

                         Could be that the Accumulo services are only
        listening
                         on localhost and not the "external" interface
        for your
                         VM. To get a connector, that's a call to a
        TabletServer
                         which run on 9997 by default (and you have open).

                         Do a `netstat -nape | fgrep 9997 | fgrep
        LISTEN` in your
                         VM and see what interface the server is bound
        to. I'd
                         venture a guess that you just need to put the
        FQDN for
                         your VM in $ACCUMULO_CONF_DIR/slaves (and masters,
                         monitor, gc, tracers, for completeness) instead of
                         localhost.
