Steve Loughran commented on YARN-8053:
--------------------------------------
we seem to be suffering a losing battle by attempting to pull in a version of
hbase built with an older version of hadoop. As well as hadoop artifacts
getting in, we can't safely upgrade things. Is there any way to unwind this
dependency by having {{hadoop-yarn-server-timelineservice-hbase}} be something
which is downstream of both, because loops shouldn't be found in DAGs?
> Add hadoop-distcp in exclusion in hbase-server dependencies for
> timelineservice-hbase packages.

> It is observed that when we change the version number of hadoop leading build
> failure because of dependency resolution conflicts for HBase-2 compilation.
> We see below error which tells that hbase-server has dependency on
> hadoop-distcp. We also need to exclude hadoop-distcp from exclusion list.
