> 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.
