---------------------------------

             Summary: Identify VOID datatype in generated table and notify the user accordingly
                 Key: HIVE-3818
                 URL: https://issues.apache.org/jira/browse/HIVE-3818
             Project: Hive
          Issue Type: Improvement
          Components: Serializers/Deserializers
            Reporter: Gary Colman
            Priority: Trivial


When using rcfile as a datastore, generating a table from a select statement with a null field results in a void data type, and throws an exception (Internal error: no LazyObject for VOID).

eg.
  set hive.default.fileformat=RCFILE;
  CREATE TABLE test_table AS SELECT NULL, key FROM src;




Make the message to the user a little more intuitive.
