> In Apache Solr, we use hadoop-auth for delegation tokens. However, because of the following
lines, we need to import Jackson (old version).
> https://github.com/apache/hadoop/blob/branch-2.7/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/token/delegation/web/DelegationTokenAuthenticationHandler.java#L279
> If we could extract out the calls to ObjectMapper to another method, so that at Solr
we could override it to do the Map -> json conversion using noggit, it would be helpful.
> Reference: SOLR-9542
