introduce complex data-type for query "Alter table tableName change columnName copyColumnName dataType"

[rahul_ku]

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) STORED BY 'carbondata' Alter table changecomplexdatatype change arrayField arrayField array

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>
