Uninstalling RPM Deployments

This topic describes how to uninstall Cloudera Data Science Workbench from a cluster.

RPM Deployments

Run the following command on the master host to stop Cloudera Data Science Workbench.
```
cdsw stop
```
note
On Cloudera Data Science Workbench 1.4.0 (and lower), do not stop or restart Cloudera Data Science Workbench without using the cdsw_protect_stop_restart.sh script. This is to help avoid the data loss issue detailed in TSB-346.
(Strongly Recommended) On the master host, backup the contents of the /var/lib/cdsw directory. This is the directory that stores all your application data.

To create the backup, run the following command on the master host:
```
tar cvzf cdsw.tar.gz /var/lib/cdsw/*
```
To uninstall Cloudera Data Science Workbench, run the following commands on the master host and all the worker hosts.
```
cdsw stop
yum remove cloudera-data-science-workbench
```
Remove all your user data that is stored in /var/lib/cdsw on the master host from the deployment. This step will permanently remove all user data.
```
sudo rm -Rf /var/lib/cdsw
```
