We have already seen in this post how you can configure Hue in your cluster. But did you know that there’s a property that can make a top banner appear in your Hue installation? This is quite useful if you want for instance to show a disclaimer to your users, or to clearly mark a testing or production environment, or if you want to display some dynamic information there. Depending on if you are using Cloudera Manager or not, you should either add a safety valve or edit a .ini file to use this feature. For details on how to change the configuration, read here. In the desktop/custom section of the ini file you can find the banner_top_html property:
[desktop] [[custom]] \# Top banner HTML code banner_top_html=
Or we could even use a very old HTML tag to display a running ticker!
[desktop] [[custom]] \# Top banner HTML code banner_top_html='
[desktop] [[custom]] \# Top banner HTML code banner_top_html=''
