Mike Drob updated HBASE-16338:
------------------------------
Attachment: HBASE-16338.v5.patch
This rabbit hole went pretty deep. I discovered that we were mix and matching
some jackson 1 and jackson 2 annotations, which would fail in interesting and
difficult to diagnose ways.
The bright side is that consumers using Jackson 1 to consume our JSON output
should largely be fine, and not need changes, since it's still well-formed JSON
from their perspective. The problem was trying to use Jackson 2 mappers with
Jackson 1 annotations, and some other bad idea combinations.
This patch ballooned in size pretty quickly from fixing the imports, so I'm
also attaching it to RB.
