Hi all,
currently "Alter table tableName change columnName copyColumnName dataType" query supports only primitive type .

I propose it should also support complex data type .

e.g.
CREATE TABLE changecomplexdatatype(arrayField array<int>) STORED BY 'carbondata'
Alter table changecomplexdatatype change arrayField arrayField array<bigint>
