Hi, I get this error when I try to start dremio on the executors

`sudo service dremio start`

```
java.lang.RuntimeException: Failure while attempting to create com.dremio.service.users.SimpleUserService.
at com.dremio.service.BinderImpl$InjectableReference.get(BinderImpl.java:427)
	at com.dremio.service.BinderImpl.lookup(BinderImpl.java:109)
	at com.dremio.service.BinderImpl$DeferredProvider.get(BinderImpl.java:83)

```

I’ve installed dremio on Amazon EC2 with a single master-coordinator node and 2 executors.  
I’ve been able to start t successfully on the master node, but it fails with the above error when I try to  
kick off the executors.

The config file for the executor looks like this:

```
services: {
  coordinator.enabled: false,
  coordinator.master.enabled: false,
  executor.enabled: true
}
zookeeper: "10.XXX.YYY.ZZZ:2181"

```

The config file for the master looks like this:

```
services: {
   coordinator: {
    enabled: true,
  master: {
      enabled: true,
      # configure an embedded ZooKeeper server on the same node as master
      embedded-zookeeper: {
        enabled: true,
        port: 2181,
        path: ${paths.local}/zk
      }
    }
},
executor: {
    enabled: false
  },
}

```

As you can see I am trying to use the internal zookeeper on the master.

I have made sure that both master and executor EC2 instances are in the same security group.

Any help you can provide will be greatly appreciated

Hi @Femi_Anthony

Couple of questions

1. The Zoo Keeper reference on the executor node (10.XXX.YYY.ZZZ:2181), is this the IP of the master node?
2. Can you please send us the server.out and server.log?

Thanks
