1 Supported for Cloudera Impala 2.1 and higher.
2 Supported for Cloudera Impala 1.4 and higher
3 Maximum of 2 GB
4 If the StringDescribeType connection property is set to varchar (the default), the String data type maps to VARCHAR. If StringDescribeType is set to longvarchar, String maps to LONGVARCHAR.
5 Supported for Cloudera Impala 2.1 and higher.
