Subject [jira] [Commented] (HBASE-16338) update jackson to 2.y
Date Fri, 20 Oct 2017 14:02:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16338?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16212670#comment-16212670
] 

Sean Busbey commented on HBASE-16338:
-------------------------------------

the shaded artifacts include incorrect services API definitions for jackson 2 at {{META-INF/services/}}
for {{com.fasterxml.jackson.core.JsonFactory}} and {{com.fasterxml.jackson.core.ObjectCodec}}.
They point at classes in their unrelocated state. They should probably just be filtered since
things appear to work. It's a relatively harmless nuisance, since if we are loaded into the
same JVM as an unrelocated Jackson 2, we point at the same implementation classes as they
will. Probably already present before this change, so I'm fine with it getting done in a follow-on.
