502 proxy error calling Zeppelin paragraph (Impala query) via REST API (fine when run via Zeppelin UI)

New Contributor

I'm calling an Impala query paragraph in a Zeppelin note, using the REST API (so I can parse the returned data in Javascript) and it works fine some of the time, and other times it fails with a 502 proxy error. The same paragraph run via the Zeppelin UI always works fine.


I'm running it synchronously as per:


How would I go about fault finding on this please? I'm unsure where to start.

Or, is there another way I can access the data, it looks to me like the asynchronous method will not return any data, just a status?
