Dremio starts Zookeeper server unless one specifies external Zookeeper server to use. Saying that - do you have Zookeeper server running on the same node (it uses port 2181 by default) or any other process running on port 2181? ---

Thanks. That was the issue. Zookeeper from Drill was running. ---

Hi, how one can point dremio to use external zookeeper? I did not find any option in /etc/dremio/dremo.conf file ---

You can check the reference for `dremio.conf` configuration file at [https://docs.dremio.com/advanced-administration/configuration-files.html#dremio-configuration-file](https://docs.dremio.com/advanced-administration/configuration-files.html#dremio-configuration-file) There are two settings of interest in your case: - `zookeeper` which points to the zookeeper quorum to use for coordination - `services.coordinator.embedded_master_zk.enabled` which turns on/off the embedded zookeeper server (running by default on port 2181) ---
