      The `hadoop-client` Maven artifact available in 2.x releases pulls
      Hadoop's transitive dependencies onto a Hadoop application's classpath.
      This can be problematic if the versions of these transitive dependencies
      conflict with the versions used by the application.

      [HADOOP-11804](https://issues.apache.org/jira/browse/HADOOP-11804) adds
      new `hadoop-client-api` and `hadoop-client-runtime` artifacts that
      shade Hadoop's dependencies into a single jar. This avoids leaking
      Hadoop's dependencies onto the application's classpath.

This avoids leaking Hadoop's dependencies onto the application's classpath.

      Description

      make a hadoop-client-api and hadoop-client-runtime that i.e. HBase can use to talk with a Hadoop cluster without seeing any of the implementation dependencies.

      see proposal on parent for details.
