Sean Busbey updated HBASE-23015:
--------------------------------
Hadoop Flags: Incompatible change
Release Note:
<!-- markdown -->
HBase has stopped including Jackson in the classpath seen by downstream users
except for as a part of running the HBase REST Service or when brought in
transitively from Apache Hadoop.
Downstream users who still need Jackson classes should include the dependency
themselves.
Resolution: Fixed
Status: Resolved (was: Patch Available)
> Replace Jackson with relocated gson everywhere but hbase-rest

> HBASE-22728 moved out jackson transitive dependencies. mostly good, but
> moving jackson2 to provided in hbase-server broke few things
> testing-util needs a transitive jackson 2 in order to start the minicluster,
> currently fails with CNFE for {{com.fasterxml.jackson.databind.ObjectMapper}}
> when trying to initialize the master.
> shaded-testing-util needs a relocated jackson 2 for the same reason
> it's not used for any of the mapreduce stuff in hbase-server, so
> {{hbase-shaded-server}} for that purpose should be fine. But it is used by
> {{WALPrettyPrinter}} and some folks might expect that to work from that
> artifact since it is present.
