> Issue Type: Bug

> 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');
> output:
> +------+--+
> | 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));
> output:
> +------------------------+--+
> | 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.
