Null displays while using limit with order by clause in sort_column

Steps to reproduced:

1) Create table:
CREATE TABLE sorttable3 (empno int, empname String, designation String, doj Timestamp, workgroupcategory
int, workgroupcategoryname String, deptno int, deptname String, projectcode int, projectjoindate
Timestamp, projectenddate Timestamp,attendance int,utilization int,salary int) STORED BY 'org.apache.carbondata.format'
tblproperties('sort_columns'='doj')

2) Load data:
LOAD DATA local inpath 'hdfs://localhost:54310/newdata.csv' INTO TABLE sorttable3 OPTIONS('DELIMITER'=
',', 'QUOTECHAR'= '\"');

3)Execute Query:
select doj from sorttable3 order by doj limit 10;

Actual Result:
+-------+--+
|  doj  |
+-------+--+
| NULL  |
| NULL  |
| NULL  |
| NULL  |
| NULL  |
| NULL  |
| NULL  |
| NULL  |
| NULL  |
| NULL  |
+-------+--+

Expected Result:
it should display ordered doj as per limit.
