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

             Summary: Show Segment command gives Null Pointer Exception after the table is
updated
                 Key: CARBONDATA-1411
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-1411
             Project: CarbonData
          Issue Type: Bug
    Affects Versions: 1.2.0
         Environment: Linux, Hadoop 2.2.0 and spark 2.1.0
            Reporter: Pallavi Singh
             Fix For: 1.2.0


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;
+--------------------+------------+--------------------------+--------------------------+--+

+--------------------+------------+--------------------------+--------------------------+--+

now after that I executed the following query :

update uniqdata set (dob)=('2016-12-31 12:00:00') where cust_name='CUST_NAME_01998';

and then again ran : show segments for table uniqdata;

And now I am getting : Error: java.lang.NullPointerException (state=,code=0)
