Hi, I have a problem when I work with Dremio in Docker. When I start the containers, after 12 seconds or so they stop, they do not keep up. I look at the logs of the stopped containers and I get this error: “Dremio is exiting. Failure while starting services. com.dremio.common.exceptions.UserException: No Cluster Identity found at com.dremio.common.exceptions.UserException $ Builder.build (UserException.java:746) at com.dremio.dac.cmd.upgrade.Upgrade.run (Upgrade.java:187) at com.dremio.dac.cmd.upgrade.Upgrade.run (Upgrade.java:179) at com.dremio.dac.daemon.DremioDaemon.main (DremioDaemon.java:104)” Does anyone know why this happens to me? I am using 1 container with the role of master, 3 containers with the role of executors and an external zookeeper to coordinate them. Thank you ---

Hi @German If this is a fresh install, delete the dB folder under data and try to start Dremio again Thanks @balaji.ramaswamy ---

Hi @balaji.ramaswamy I have deleted the db folder under data and the container is still standing alone, and in the logs of the container the same thing keeps coming up. I am trying to test the yarn provisioning and have followed the instructions of the [docs page](https://docs.dremio.com/deployment/yarn-hadoop.html). Before modifying the dremio.conf and adding the core-site.xml, hdfs-site.xml and yarn-site.xml files to the conf folder, everything seemed to work fine. I tried to build another 4 docker containers without those modifications and I have no problem. Thanks for the help. ---

Hi @German Can you please send us the server.out and server.log? (The one that has the error) Thanks @balaji.ramaswamy ---

Hi @balaji.ramaswamy In the end I realized that I was doing things wrong, what I have to do is in a container with Hadoop install Dremio inside and test the YARN provisioning. Thank you
