Is there a way to clear memory of Zeppelin?

I am noticing that Zeppelin is consuming a lot of memory even when I am not running any paragraph. It seems, it caches some data in the memory somehow. Is there any way to clear such memory?

Solution

  • From the following URL: https://community.hortonworks.com/questions/104408/how-to-clear-values-in-zeppelin-notebook.html

    Zeppelin stores [cached variables] in a file called note.json. This file is usually stored inside of a directory (the note's ID is usually in the URL for the note, and is the subdirectory name) on the Zeppelin home server, and can be edited in a text editor where you can remove the values/paragraphs if you so require.

    Here is a good post showing how to do it: https://community.hortonworks.com/questions/24254/zeppelin-how-to-remove-results-cache-from-notebook.html

    This should help clear up some of the memory for you.
