>             Project: CarbonData
>          Issue Type: Bug
>          Components: sql
>    Affects Versions: 1.3.0
>         Environment: 3 node ant cluster

> Steps:
> User creates a table with char datatype --> Create table is success.
> 0: jdbc:hive2://10.18.98.34:23040> CREATE TABLE sensor_reading_blockblank_false(id char)  STORED BY 'carbondata';
> +---------+--+
> | Result  |
> +---------+--+
> +---------+--+
> No rows selected (0.688 seconds)
> User tries to alter the table using column name for char datatype in the same way.
> alter table sensor_reading_blockblank_false add columns(id1 char);
> Issue : Alter table fails with parsing error as shown below
> 0: jdbc:hive2://10.18.98.34:23040> alter table sensor_reading_blockblank_false add columns(id1 char);
> Error: java.lang.RuntimeException:
> BaseSqlParser>>>>
> Operation not allowed: alter table add columns(line 1, pos 0)
> == SQL ==
> alter table sensor_reading_blockblank_false add columns(id1 char)
> ^^^
> CarbonSqlParser>>>> [1.65] failure: ``('' expected but `)' found
> alter table sensor_reading_blockblank_false add columns(id1 char)
>                                                                 ^ (state=,code=0)
> Similar consistency issue is observed for varchar data type create table and alter table usage.
> 0: jdbc:hive2://10.18.98.34:23040> CREATE TABLE sensor_reading_blockblank_false(id varchar)  STORED BY 'carbondata';
> +---------+--+
> | Result  |
> +---------+--+
> +---------+--+
> No rows selected (0.244 seconds)
> 0: jdbc:hive2://10.18.98.34:23040> alter table sensor_reading_blockblank_false add columns(id1 varchar);
> Error: java.lang.RuntimeException:
> BaseSqlParser>>>>
> Operation not allowed: alter table add columns(line 1, pos 0)
> == SQL ==
> alter table sensor_reading_blockblank_false add columns(id1 varchar)
> ^^^
> CarbonSqlParser>>>> [1.68] failure: ``('' expected but `)' found
> alter table sensor_reading_blockblank_false add columns(id1 varchar)
>                                                                    ^ (state=,code=0)
> Expected : The create table and alter table output should be consistent for char and varchar types for similar syntax usage.
