Péter Gergő Barna commented on ATLAS-2310:
------------------------------------------
An actual occurrence of this problem when Atlas runs in HA mode and the
hive-import.sh fails with HTTP status 400 (Bad Request) Response Body
({"error":"Entity type cannot be null"}) because the /api/atlas/entities
request is being sent to the passive node which redirects the request to the
active node with the wrong URL encoding.
logs, passive node:

> In HA, the passive node redirects the request with wrong URL encoding.
> Instead of encoding only the values, the whole query is encoded as a single
> string.
> url = "http://atlas.node.com:21000/api/atlas/entites?type=My type&name=My
> name"
> wrong result after encoding:
> http://atlas.node.com:21000/api/atlas/entites?type%3DMy+type%26name%3DMy+name
> expected result after encoding:
> http://atlas.node.com:21000/api/atlas/entites?type=My%20type&name=My%20name
> in the code, instead of

> queryString = URLEncoder.encode(queryString, "UTF-8");
