> Getting null pointer exception while loading data into table and while fetching data getting NULL values
> 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://localhost:54310/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','TIMESTAMPFORMAT'='yyyy-mm-dd hh:mm:ss');
> 3) Expected result: it should load data into table successfully.
> 4) Actual Result: it throws an error
> Error: java.lang.NullPointerException (state=,code=0)
> logs:
