-------------------------------
Summary: The total number of load data is not correct when use preaggregate datamap
Key: CARBONDATA-3758
URL: https://issues.apache.org/jira/browse/CARBONDATA-3758
Project: CarbonData
Issue Type: Bug
Components: data-query
Affects Versions: 1.5.4
Environment: centos 7 spark2.3.3 jdk8 carbondata-1.5.5

For exmaple:
a query like 'select sex, count(sex) from carbon_test grou by sex;', the query return two rows like this :
----------------------------
sex | count(sex) |
------------------------------
male | 374521458 |
-----------------------------
female | 225478542 |
-----------------------------------
male + female= 600000000
total is 600000000
another query is select count(\*) from carbon_test ,the result is
------------------------------
count(\*) |
----------------------------
500000000 |
--------------------------------
male + female > count(\*)
so it is wrong
