> *Issue:*
> <= filter is giving wrong results for timestamp dictioinary column
> *Steps to reproduce:*
> (1) Create a table with a timestamp dictionary column
> create table t1(dob timestamp) stored by 'carbondata' TBLPROPERTIES ('DICTIONARY_INCLUDE'='dob')
> (2) Load data
> 1970-01-01 05:30:00 (same value as 300 records)
> (3) Apply filter on table
> select count(*) from t1 where dob=cast('1970-01-01 05:30:00' as timestamp);
> +--------+
> |count(1)|
> +--------+
> |300     |
> +--------+
> select count(*) from t1 where dob<=cast('1970-01-01 05:30:00' as timestamp);
> +--------+
> |count(1)|
> +--------+
> |1         |
> +--------+
> Both the queries should give us the same results.
> Solution:
> In less than equal to filter, we are considering surrogate 2 as default value. But surrogate 1 is for default value.
