Subject [jira] [Created] (PHOENIX-5188) IndexedKeyValue should populate KeyValue fields

             Summary: IndexedKeyValue should populate KeyValue fields
                 Key: PHOENIX-5188
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5188
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.14.1, 5.0.0
            Reporter: Geoffrey Jacoby
            Assignee: Geoffrey Jacoby


IndexedKeyValue subclasses the HBase KeyValue class, which has three primary fields: bytes,
offset, and length. These fields aren't populated by IndexedKeyValue because it's concerned
with index mutations, and has its own fields that its own methods use. 

However, KeyValue and its Cell interface have quite a few methods that assume these fields
are populated, and the HBase-level factory methods generally ensure they're populated. Phoenix
code should do the same, to maintain the polymorphic contract. This is important in cases
like custom ReplicationEndpoints where HBase-level code may be iterating over WALEdits that
contain both KeyValues and IndexKeyValues and may need to interrogate their contents. 

Since the index mutation has a row key, this is straightforward.
