Hi,

Recently I'm doing some tests on spark2.1.0+carbondata1.0.0 and have some questions:

1)Exception is thrown when table created without any dictionary column. Does that means carbon table must have at least one dictionary column?

2)What's the connection between dictionary-encoded column and MDK? Does MDK only contains dictionary-encoded column?
