ishnagy opened a new pull request, #6146:
URL: https://github.com/apache/hive/pull/6146

   ### What changes were proposed in this pull request?
   
   I am proposing to remove the tight dependency coupling between `hive-exec` 
and `hadoop-yarn-registry` (to address HIVE-29284).
   
   
   ### Why are the changes needed?
   
   `hive-exec` pulls in `hadoop-yarn-registry` as a direct dependency, but 
registry classes are only used for building a local resource map for LLAP. This 
map can be built without the actual class instances getting loaded, using class 
name literals only. Removing `hadoop-yarn-registry` as a direct dependency will 
prevent pulling in its whole transitive dependency tree when one only wants to 
use `hive-exec` functionality without LLAP. (e.g apache spark)
   
   
   ### Does this PR introduce _any_ user-facing change?
   No
   
   ### How was this patch tested?
   This patch will be tested by the pre merge tests executed for this pull 
request.
