Subject [jira] [Commented] (HADOOP-13332) Remove jackson 1.9.13 and switch all jackson code to 2.x code line
Date Mon, 03 Apr 2017 19:01:41 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15954013#comment-15954013

Vrushali C commented on HADOOP-13332:

Thanks [~busbey].
bq. It would be helpful to the hbase project if you could detail why you need the hbase-server
jar in the first place, presuming it isn't for some kind of mapreduce integration.
We have a coprocessor on one of the tables that extends BaseRegionObserver. So packages like
org.apache.hadoop.hbase.coprocessor and org.apache.hadoop.hbase.regionserver packages have
to be imported. 

We would like to add this utility kind of coprocessor in hbase itself so that timeline service
v2 can use it as a client HBASE-17273.
