Description

When Using Livy to Interact with Spark , the Spark Response with German Special Character always return with jumbled Characters(Wrong characters) after patching the ZEPPELIN-2641

The Initial Issue was We were hitting ZEPPELIN -2641 . But after Patching the fix provided in ZEPPELIN-2641 the exception stopped but the special characters obtained is not correct( wrong characters)

This happens for German Special Characters like ß, ü, Ü, ä, Ä, ö, Ö .

The Reason is Zeppelin uses restTemplate.java from spring framework. when POST/GET the request we need to tell restTemplate to use StringHttpMessageConvertersion technique to UTF-8.

Attached the patch with Jira with which the Special characters shows fine.
