             Summary: Make Jetty's requestHeaderSize configurable in Spark
                 Key: SPARK-26118
                 URL: https://issues.apache.org/jira/browse/SPARK-26118
             Project: Spark
          Issue Type: Improvement
          Components: Web UI
    Affects Versions: 2.4.0, 2.3.2, 2.2.2, 2.1.3, 3.0.0
            Reporter: Attila Zsolt Piros


For long authorization fields the request header size could be over the default 
limit (8192 bytes) and in this case Jetty replies HTTP 413 (Request Entity Too 
Large).

This issue may occur if the user is a member of many Active Directory user 
groups.

The HTTP request to the server contains the Kerberos token in the 
WWW-Authenticate header. The header size increases together with the number of 
user groups. 

Currently there is no way in Spark to override this limit.
