-----------------------------------------

             Summary: Drop partition is dropping table data
                 Key: CARBONDATA-1989
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-1989
             Project: CarbonData
          Issue Type: Bug
          Components: data-query
    Affects Versions: 1.3.0
         Environment: spark2.1
            Reporter: Geetika Gupta
             Fix For: 1.3.0
         Attachments: 2000_UniqData.csv

I created table using:
CREATE TABLE uniqdata_string(CUST_ID int,CUST_NAME String,DOB timestamp,DOJ timestamp, BIGINT_COLUMN1 bigint,BIGINT_COLUMN2 bigint,DECIMAL_COLUMN1 decimal(30,10),DECIMAL_COLUMN2 decimal(36,10),Double_COLUMN1 double, Double_COLUMN2 double,INTEGER_COLUMN1 int) PARTITIONED BY(ACTIVE_EMUI_VERSION string) STORED BY 'org.apache.carbondata.format' TBLPROPERTIES ('TABLE_BLOCKSIZE'= '256 MB');

Load command:
LOAD DATA INPATH 'hdfs://localhost:54311/2000_UniqData.csv'
into table uniqdata_string partition(active_emui_version='abc') OPTIONS('FILEHEADER'='CUST_ID,CUST_NAME
,ACTIVE_EMUI_VERSION,DOB,DOJ,
BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,
Double_COLUMN2,INTEGER_COLUMN1','BAD_RECORDS_ACTION'='FORCE');

LOAD DATA INPATH 'hdfs://localhost:54311/2000_UniqData.csv'
into table uniqdata_string partition(active_emui_version='xyz') OPTIONS('FILEHEADER'='CUST_ID,CUST_NAME
,ACTIVE_EMUI_VERSION,DOB,DOJ,
BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,
Double_COLUMN2,INTEGER_COLUMN1','BAD_RECORDS_ACTION'='FORCE');

show partitions command:
show partitions uniqdata_string;

Output:
0: jdbc:hive2://localhost:10000> show partitions uniqdata_string_new;
--------------------------+
partition
--------------------------+
active_emui_version=abc
active_emui_version=xyz
--------------------------+

select query:
0: jdbc:hive2://localhost:10000> select count(*) from uniqdata_string_new;
+-----------+--+
| count(1)  |
+-----------+--+
| 4026      |
+-----------+--+

Drop partition query:
alter table uniqdata_string_new drop partition(active_emui_version='xyz');

show partitions uniqdata_string_new;
+--------------------------+--+
|        partition         |
+--------------------------+--+
| active_emui_version=abc  |
+--------------------------+--+

Select query:
0: jdbc:hive2://localhost:10000> select count(*) from uniqdata_string_new;
+-----------+--+
| count(1)  |
+-----------+--+
| 2013      |
+-----------+--+

Previously there were 4026 records and after dropping the partition, the records got reduced to 2013.
