My experience is that to save to S3, you don't need to press that button at all. Just executing any paragraph seems to be enough, doesn't matter which interpreter. I often run a markdown paragraph if I want to save spark code that I am not ready to execute. That button is more of a workbook reload

Dropbox, Box, Steam, etc handle syncing of files between devices and cloud storage without the need for a refresh button at all, but I guess it would be a big job to replicate this behaviour in Zeppelin. From: Partridge, Lucas (GE Aviation) Sent: 25 July 2017 10:10 To: users@zeppelin.apache.org Subject: EXT: "Reload notes from storage" button overwrites recent edits When a user clicks on this button on the Zeppelin homepage: [Screen Clipping] …which notebooks are reloaded from storage: all the notebooks, or only the notebooks that belong to the user who clicked the refresh button? Unfortunately in our setup, where all the notebooks are backed up on S3, it appears to be all the notebooks. This means that if any user on the multi-user system hits that button, then any notebook edits made since the last backup to S3 made by any user will be overwritten by the old copies. This is immensely frustrating for the users who lose their edits! So, is this a known issue in Zeppelin; or is there a recommended way of syncing with S3 so that only the notebooks of the user who hits that button get refreshed? BTW when the sync with S3 or wherever occurs, aren’t the timestamps of the individual files compared first to determine which ways the files should be copied? If the S3 copy is newer then the local notebook should be overwritten (assuming times are in sync between the zeppelin host and S3). If the local copy is newer than that should be used to overwrite the copy in S3. If this process were followed then it wouldn’t matter if everyone’s notebooks were updated when someone hits that button. This assumes Zeppelin can tell if someone is actively editing a paragraph that hasn’t even been executed yet though.
