> Below problems need to be addressed through this jira.
> 1. Temp store location path formation for compaction through sort step is incorrect. Temp store location key being formed is not proper.
> 2. Data type change validations:
> a. New precision should always be greater than existing precision
> b. New scale value can be same as old scale value.
> 3. Filter query bug on datatype changed for a decimal column. Steps to reproduce:
> create table alter_decimal_filter (n1 string, n2 int, n3 decimal(3,2)) stored by 'carbondata';
> insert into alter_decimal_filter select 'xx',1,1.22;
> insert into alter_decimal_filter select 'xx',1,1.23;
> alter table alter_decimal_filter change n3 n3 decimal(8,4);
> insert into alter_decimal_filter select 'dd',2,111.111;
> select * from alter_decimal_filter where n3 = 1.22;
