Setting the cache timeout

Enable Hue UI caching by setting a timeout in milliseconds. The default is 86400000 milliseconds or one day. Set the timeout to 0 to disable caching.

You can set the cache timeout using the cacheable_ttl property under the [desktop][[custom]] section in the Hue Service Advanced Configuration Snippet (Safety Valve) for hue_safety_valve.ini configuration property in Cloudera Manager.

Log in to Cloudera Manager as an Administrator.
Go to Clusters > Hue > Configuration
In the Search text box, type hue_safety_valve.ini to locate the Hue Service Advanced Configuration Snippet (Safety Valve) for hue_safety_valve.ini configuration parameter.
Add the following parameters with the cache timeout value to the Hue Service Advanced Configuration Snippet (Safety Valve) for hue_safety_valve.ini configuration parameter:
```
[desktop]
[[custom]]
cacheable_ttl=[***VALUE-IN-MILLISECONDS***]
```
For example, the following configuration sets the cache timeout to the default value of 86400000 milliseconds:
```
[desktop]
[[custom]]
cacheable_ttl=86400000
```
Click Save Changes.
Restart the Hue service.
