Review comment:
Instead of creating a second variable and exporting here, you can probably
just execute it with the environment variable set for the execution:
```suggestion
$SSH "$host" "bash -c
'ACCUMULO_SERVICE_INSTANCE='"$ACCUMULO_SERVICE_INSTANCE"'
${bin}/accumulo-service \"$service\" \"$control_cmd\"'"
```
