Major Description
HCatalog is bundled with Hive in the newer releases of hive. Consequently, it's packaging code should reside in Hive's packaging directories (and it already does).
Consequently, we are not using https://github.com/apache/bigtop/tree/master/bigtop-packages/src/common/hcatalog
and the corresponding locations in rpm and deb directories which used to package HCatalog before it was a part of hive.
So, we should get rid of those directories. Also, we should check in bigtop.mk and make sure no references to building HCatalog remain. The only way, we should be able to build HCatalog should be via Hive.
