Prasanth Jayachandran commented on HIVE-20071:
----------------------------------------------

We already have a enforcer plugin that can have banned dependencies (direct or 
transitive). You can refer .2 patch from HIVE-20019 which avoids direct 
dependency. .1 patch avoids transitive as well. Not sure what the new plugin 
provides in addition to the enforcer plugin. Maybe we should use enforce plugin 
for jackson usage as well?

> Migrate to jackson 2.x and prevent usage
