> Displaying a newly created column family with column_metadata displays some kind of hex
representation of the column names instead of something more human readable:

> [default@test] create column family Foo3 with column_metadata = [{ column_name: mycolumn,
validation_class: UTF8Type }, { column_name: mycolumn2, validation_class: UTF8Type }];
