> I created a 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")
> and loaded the table :
> LOAD DATA inpath 'hdfs://localhost:54310/data/2000_UniqData.csv' INTO table uniqdata options('DELIMITER'=',', 'FILEHEADER'='CUST_ID, CUST_NAME, ACTIVE_EMUI_VERSION, DOB, DOJ, BIGINT_COLUMN1, BIGINT_COLUMN2, DECIMAL_COLUMN1, DECIMAL_COLUMN2, Double_COLUMN1, Double_COLUMN2, INTEGER_COLUMN1')
> I loaded the table 7 times using multiple cvs.
> Then executed the following command :
> show segments for table uniqdata;
> and output was :
> 0: jdbc:hive2://localhost:10000> show segments for table uniqdata;

> and then again ran : show segments for table uniqdata;
> And now I am getting : Error: java.lang.NullPointerException (state=,code=0)
