expected condition of attribute exists=true does not work

[Charles Wang]

In conditional operations, the expected condition doesn't work when checking an attribute exists in the table.

    "expected": {
        "my_table_attr": {
            "exists": true
        }
    }

would generate CQL query string like this:

    IF attr_exist={'Subject'}

where attar_exist has the value of {'Author', 'Body', 'DateTime', 'MessageId', 'Subject'}.

The corresponding CQL statement failed with Cassandra 2.0.7.

The collection type supports CONTAINS in Cassandra 2.1. See the following issue fixed in Cassandra 2.1 beta1:
