-----------------------------------------
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)
