I noticed that whenever I install the docker quickstart, run cloudera manager on it and then start the cluster, I see that the following services are red:
Bad : Master summary: quickstart.cloudera (Availability: Active, Health: Bad). This health test reflects the health of the active Master.
Bad : This RegionServer is not connected to its cluster.
Bad : This role's process exited. This role is supposed to be started.
Bad : NameNode summary: quickstart.cloudera (Availability: Active, Health: Bad). This health test reflects the health of the active NameNode.
Bad : ResourceManager summary: quickstart.cloudera (Availability: Active, Health: Bad). This health test reflects the health of the active ResourceManager.
My virtual machine is running Ubuntu 14.04, has 24 GB memory, 8 cores, 250 GB Storage. I am using the latest docker cloudera image using
docker pull cloudera/quickstart:latest
Also, I am installing JDK 1.8 before I run
To install the JDK: I set the JAVA_HOME variable to the new path, upgrade /etc/profile to reflect the change and also add it to /etc/default/bigtop-utils. Once the Cloudera Manager is up, I update the Hosts Configuration with this change as well.
Currently the latest docker image has CDH 5.7.
What can I do to have all services in green upon running Cloudera quickstart?

Thanks for the info! Are there detailed steps for installation? I tried it, and it installs a container, which if I run starts a python shell. It would be good to have some detailed installation documentation on this.

Thanks @dspivak. One last question: I see that clusterdock created 2 nodes. Are these virtual nodes?
My cluster itself has 2 nodes, each has 24 GB memory and 8 Cores. So:
1) How do I know if each of my physical node is being used as a clusterdock node.
2) Is there a way to map them?
3) Is there a way to create more than 2 nodes using clusterdock?
Again, thanks for your help!
