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
If this is a fresh install, delete the dB folder under data and try to start Dremio again
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. 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.
Has anyone found any solution for this?
Can you please send us the server.out and server.log? (The one that has the error)
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
