Can you share the `dremio.conf` for the coordinator _and_ the executors. The _executor_ should have this configuration: ```auto services: { coordinator: { enabled: false master: { enabled: false } } executor: { enabled: true } } ``` ---

My executor is like this: ``` paths: { # the local path for dremio to store data. local: "/var/lib/dremio" # the distributed path Dremio data including job results, downloads, uploads, etc #dist: "pdfs://"${paths.local}"/pdfs" } services: { coordinator.enabled: false, coordinator.master.enabled: false, executor.enabled: true } zookeeper: "coordinator:2181" ``` It is wrong? ---

@victorbertoldo, this: `zookeeper: "coordinator:2181"` would only be correct if `coordinator` is indeed the hostname of the Dremio coordinator. For that value, you want the internal IP or some hostname for the coordinator that is resolvable from executor. ---

Thats the hostname indeed. ---
