Before you begin installing Cloudera Data Science Workbench, make sure you have
completed the steps to secure your hosts, set up DNS subdomains, and configure block
devices.
note
You should configure your system journal so that the message file does
not grow unchecked. For example, the following sets the maximum size of
/var/log/message to 500MB and older log files will be kept until
the sum of all message files' sizes exceed
4GB.
cat /etc/systemd/journald.conf |grep System
SystemMaxUse=4G
SystemMaxFileSize=500M
For information on performing these prerequisite tasks, see: Required Pre-Installation Steps
note
For proof-of-concept deployments, you can deploy a 1-host cluster with just a Master
host. The Master host can run user workloads just as a worker host can when required for
demonstration purposes. For production deployments, you must have a reserved, dedicated
master host and separate worker host(s).
