Sean Busbey commented on HBASE-26871:
-------------------------------------
the test run of nightly didn't run the integration test against hadoop 2. looks
like the branch mapping never got updated for the change to feature branch
naming required by how asf infra does branch protection. I'll push an update on
the branch and make sure we have a Jira long term.
> shaded mapreduce and shaded byo-hadoop client artifacts contains no classes
