I experience the same. It appears to be a problem with the websockets (ws:// or wss://) connections.

I directly deployed a HDP3.0 cluster instead of upgrading a 2.6 cluster. Thanks.

If so, this may be due to the versioned data directory not getting the updated service definition for zeppelin. Locate the previous version and the new version data directories and track down the zeppelin service definitions within data/services/zeppelin and compare the rewrite rules.

Any idea? Appreciate any clue.
