Github user necosta commented on the issue: https://github.com/apache/zeppelin/pull/2446 @1ambda , apologies just found an issue. When helium.json is populated (and we have a non-empty list of enabled packages), immediately after we start Zeppelin, the enabledPackages REST API returns 0 when it should return the list of enabled packages from helium.json file. The bug is on getAllEnabledPackages() where it looks all allPackages which is not initialized. I'll fix this by initializing allPackages in Helium constructor.
