Installation

Known installation issues.

  • During the Cloudera Data Science Workbench startup process, you might see certain timeout issues.
    Pods not ready in cluster default ['role/<pod_name>'].
    This is due to an issue with some pods taking longer to start up and other dependent processes timing out. Restart the CDSW service to get past this issue.

  • There is an issue with installing CDSW in an airgapped environment where docker service has no access to the k8s docker repository or has no proxy set. .

    Workaround:

    The following steps must be executed after deploying the CDSW parcel and DOCKER role is started but the MASTER, APPLICATION, and WORKER roles are not yet started. In case of an RPM install, this needs to be done after starting the dockerd service but before starting the CDSW master node.

    1. Pull the missing etcd image to local docker repo in a node that has access to the k8s.gcr.io docker repository.
      # docker pull k8s.gcr.io/etcd:3.3.15-0
    2. Save the missing etcd image.
      # docker save k8s.gcr.io/etcd:3.3.15-0 -o etcd.tar
    3. Copy tarball to the CDSW master node.
      # scp etcd.tar <user>@<node>:<location>/etcd.tar
    4. SSH in to the CDSW master node and load the image to the local docker repo.
      # docker load -i <location>/etcd.tar

    Now you can start the rest of the roles for parcel installs and bring up cdsw cluster in case of an rpm install.
