Accumulo chooses the network interface to bind given the resolution of
the hostname that you provide in the "hosts" files in ACCUMULO_CONF_DIR.
If you have "localhost" (the default) still in the files (e.g. masters,
slaves), this presumably resolves to 127.0.0.1 which will result in
Accumulo not accepting connections from your VM's network adapter.
A quick hack would be to put "0.0.0.0" in those files instead of
"localhost". I think the Accumulo scripts only have the ability to
override the bound interface for the Monitor, not all processes, to be
0.0.0.0. You could also use a hostname you define in /etc/hosts that
binds to the proper interface instead (which would be a bit more like
reality).

All,
I have used Accumulo before, but a few versions ago (1.5.1), maybe
something has changed. Also, I've never before run it in a VM.
I am running Accumulo from withn a VM and attempting to connect from
without. I am getting a complaint regarding port 9997, which, within
the VM, is listening on 127.0.0.1:9997 <http://127.0.0.1:9997>.
Apparently, I need to get it onto 0.0.0.0:9997 <http://0.0.0.0:9997>.
Am I correct?
Hadoop 2.6.2
Zookeeper 3.4.10
Accumulo 1.8.1
Thrift 0.10.0
Ubuntu 16.04 as a VBox guest
OSX 10.12.06 as the host
The HAZ is running on the VM. From the CLI I can connect with the
Zookeeper client and the Accumulo client.
I have ports 22, 50070, 50075, 2181, 9995, and 9997 forwarded.
From the host, I can browse the Hadoop and Accumulo web pages. I can
also connect using the Zookeeper client. When I try to connect from
Java, I am getting a successful connect to 2181, but it complains about
port 9997.
The VM is showing all forwarded ports as listening on 0.0.0.0
<http://0.0.0.0>:<port> except for 127.0.0.1:9997
<http://127.0.0.1:9997>. As best I can tell Thrift needs the port.
My connect code:
String instance= properties.getProperty(ACCUMULO_INSTANCE);
String uri = properties.getProperty(ZOOKEEPER_URI);
Instance inst = new ZooKeeperInstance(instance, uri);
String user = properties.getProperty(USER);
String password = properties.getProperty(PASSWORD);
AuthenticationToken token = new PasswordToken(password);
conn = inst.getConnector(user, token);

It then continues to try to connect to no avail.
