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

             Summary: Abnormal behavior of timestamp data type in carbondata
                 Key: CARBONDATA-1664
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-1664
             Project: CarbonData
          Issue Type: Bug
          Components: data-query
    Affects Versions: 1.3.0
         Environment: spark 2.1
            Reporter: Vandana Yadav
         Attachments: 2000_UniqData.csv

Abnormal behavior of timestamp data type in carbondata

Steps to Reproduce:

1) Create Table:
CREATE TABLE uniqdata (CUST_ID int,CUST_NAME String,ACTIVE_EMUI_VERSION 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) STORED BY 'org.apache.carbondata.format' TBLPROPERTIES ("TABLE_BLOCKSIZE"= "256 MB")

2)Load Data:
LOAD DATA INPATH 'HDFS_URL/BabuStore/Data/uniqdata/2000_UniqData.csv' into table uniqdata OPTIONS('DELIMITER'=',' , 'QUOTECHAR'='"','BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1')

3) Execute Query:
a) select DOB from UNIQDATA where DOB ='1970-01-01 10:00:03.0' or DOB = '1970-01-04 01:00:03.0';
output:
+------------------------+--+
|          DOB           |
+------------------------+--+
| 1970-01-01 10:00:03.0  |
| 1970-01-04 01:00:03.0  |
+------------------------+--+

b) select DOB from UNIQDATA where DOB in ('1970-01-01 10:00:03.0','1970-01-04 01:00:03.0');
+------+--+
| DOB  |
+------+--+
+------+--+

c)select DOB from UNIQDATA where DOB in (cast('1970-01-01 10:00:03.0' as timestamp),cast('1970-01-04 01:00:03.0' as timestamp));
+------------------------+--+
|          DOB           |
+------------------------+--+
| 1970-01-01 10:00:03.0  |
| 1970-01-04 01:00:03.0  |
+------------------------+--+

Abnormality of timestamp datatype:
In the select query (a) it fetch the records containing DOB  1970-01-01 10:00:03.0 and 1970-01-04 01:00:03.0 but for query (b) while using IN operator it shows no data and again in the same query when we cast it to timestamp as in query (c) it displays result.

There should be a strict type checking for timestamp values.
