This means a problem talking to the oauth endpoint.

The endpoint for token refresh is wrong; the web site at the far end is returning HTML, which breaks the JSON parser. Fix: get the right endpoint from the web UI; make sure it ends in oauth2/token.
If there is a proxy betwen the application and ADL, make sure that the JVM proxy settings are correct.
The name of the ADL container is wrong, and does not resolve to any known container.

See “Adding the service principal to your ADL Account”.
The timeout used by the ADL SDK can be overridden with the hadoop property adl.http.timeout. Some timeouts in compute frameworks may need to be addressed by lowering the timeout used by the SDK. A lower timeout at the storage layer may allow more retries to be attempted and actually increase the likelihood of success before hitting the framework’s timeout, as attempts that may ultimately fail will fail faster.
