> I believe this may be because when we do a accumulo-cluster start, all of
the tservers start up with the short hostname. When I restart a server using
accumulo-service tserver start on the nodes where a tserver fell over, then it
start with the fully qualified hostname instead. Hence the monitor may not be
figuring out that the tserver has been restarted.
Do you mean the hostname you're specifying in the accumulo-cluster's
`conf/cluster.yaml` file is different from the hostname that is automatically
determined by Accumulo? Is the monitor showing the newly started servers with
their FQDN?
If you can confirm this is being caused by that discrepancy on how the
server is identified, that would be helpful. However, if that is the case, I'm
not sure there's much we can do about this, because it's possible you could
have one host named "something" and another host named "something.else", and
Accumulo has no way of knowing whether "something" and "something.else" are the
same hosts or separate. That's up to the name service, which might not even be
configured the same on every node. Accumulo just has to use what is provided in
the config, or else try to auto-discover it on the node.
If you prefer the short name, you could try starting with the preferred
short name on the host. That's all the `accumulo-cluster` script does, getting
the preferred name from its config file. But, the `accumulo-service` script is
much simpler, and isn't aware of the config file. It just does what it's
explicitly told to do. If not provided a preferred name, it will try to
auto-discover it. You can specify it using:
```bash
$ bin/accumulo-service tserver start -o general.process.bind.addr=$(hostname
-s)
```
Or, you can set `general.process.bind.addr` in `conf/accumulo.properties` to
use an environment variable, as in
`general.process.bind.addr=${env:SHORTHOSTNAME}`, and set the environment in
`conf/accumulo-env.sh` with something like `SHORTHOSTNAME=$(hostname -s)`
(Note: the configuration for the bind address name replaces the old `-a`
command you might be familiar with. In future, we'll probably add a new config
option to specify the advertisement address separately from the bind address.
Right now, the service advertisement address assumes that it's the same as the
bind address, as it did with `-a`.)
