Upgrading to Cloudera Data Science Workbench 1.10.2 on HDP

This topic contains information on upgrading to Cloudera Data Science Workbench 1.8.0.

Before you start upgrading Cloudera Data Science Workbench, read the Cloudera Data Science Workbench Release Notes relevant to the version you are upgrading to.

Run the following command on all Cloudera Data Science Workbench hosts (master and workers) to stop Cloudera Data Science Workbench.
```
cdsw stop
```
(Strongly Recommended) On the master host, backup all your application data that is stored in the /var/lib/cdsw directory.
To create the backup, run the following command on the master host:
```
tar cvzf cdsw.tar.gz /var/lib/cdsw/*
```
Save a backup of the Cloudera Data Science Workbench configuration file at/etc/cdsw/config/cdsw.conf.
Uninstall the previous release of Cloudera Data Science Workbench. Perform this step on the master host, as well as all the worker hosts.
```
yum remove cloudera-data-science-workbench
```
Install the latest version of Cloudera Data Science Workbench on the master host and on all the worker hosts. During the installation process, you might need to resolve certain incompatibilities in cdsw.conf. Even though you will be installing the latest RPM, your previous configuration settings in cdsw.conf will remain unchanged. Depending on the release you are upgrading from, you will need to modify cdsw.conf to ensure it passes the validation checks run by the 1.10.2 release.
To install the latest version of Cloudera Data Science Workbench, follow the same process to install the package as you would for a fresh installation.
