    Description

      Atlas server overwrites the entities when entity create message is sent with duplicate ID.

      In this case, HiveHook uses system.nanotime() for generating the ID for entities which does not guarantee the uniqueness of ID string. So, hiveHook creates an entity with duplicate id for columns(not all times) - which results in overwriting the columns and hence duplicate columns are seen.

      For example: One such entity create message seen from hiveHook is

      {
