---------------------------------------
Summary: hadoop-common exports logback as a transitive dependency
Key: HADOOP-19084
URL: https://issues.apache.org/jira/browse/HADOOP-19084
Project: Hadoop Common
Issue Type: Bug
Components: build
Affects Versions: 3.4.0, 3.5.0
Reporter: Steve Loughran
this is probably caused by HADOOP-18613:
ZK is pulling in some extra transitive stuff which surfaces in applications
which import hadoop-common into their poms. It doesn't seem to show up in our
distro, but downstream you get warnings about duplicate logging stuff

proposed: exclude the zk dependencies we either override outselves or don't
need.
