Noble Paul commented on HADOOP-13672:
-------------------------------------
The point is, we do not want to use jackson at all, because Solr uses another
library. if the method is extracted out, it is an easy win without any effort
from your side
> Extract out jackson calls into an overrideable method in
> DelegationTokenAuthenticationHandler

> URL: https://issues.apache.org/jira/browse/HADOOP-13672
> Project: Hadoop Common
> Issue Type: Improvement
> Reporter: Ishan Chattopadhyaya
> Priority: Minor
>
> 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
