[jira] [Created] (METRON-932) Change HLLP Stellar functions to accept empty lists

Michael Miklavcic created METRON-932:

             Summary: Change HLLP Stellar functions to accept empty lists
                 Key: METRON-932
                 URL: https://issues.apache.org/jira/browse/METRON-932
             Project: Metron
          Issue Type: Improvement
            Reporter: Michael Miklavcic
            Assignee: Michael Miklavcic


The current implementation, which disallows merging empty sets, makes interactions via the Profiler more complex than they need to be. This Jira would change the argument handling to allow empty lists. The resulting functionality should treat cardinality of a null set as zero.
