---------------------------------
Hi [~templedf],
Part of Hadoop switched to com.fastxml version of jackson in Hadoop 3, but some
parts were left in the old version. I am not sure com.fastxml.* and
org.codehaus.jackson.jaxrs can mix well. Can the code apply jaxb from the new
library?

<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
