> add JacksonUtil to centralise some code
> ---------------------------------------
>
> Key: HADOOP-19231
> URL: https://issues.apache.org/jira/browse/HADOOP-19231
> Project: Hadoop Common
> Issue Type: Task
> Reporter: PJ Fanning
> Priority: Major
> Labels: pull-request-available
>
> To future proof Hadoop against Jackson changes, it makes sense to not just
> create ObjectMappers and JsonFactories in many different places in the Hadoop
> code.
> One of the main drivers of this is
> https://www.javadoc.io/doc/com.fasterxml.jackson.core/jackson-core/latest/com/fasterxml/jackson/core/StreamReadConstraints.html
>
> Jackson 3 (not yet scheduled for release) has some fairly big API and
> behaviour changes too.
