Description

I am using update functionality with the rand(1) and rand() which return deterministic value or random value.

But as I run query it gives error.

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");

Load Data : LOAD DATA INPATH 'hdfs://localhost:54310/2000_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','MAXCOLUMNS'='12');

Query-1 : Update uniqdata set (decimal_column1) = (rand());

Query-2 : Update uniqdata set (decimal_column1) = (rand(1));

Expected Result : Update column with random value.

Actual Result :Error: java.lang.RuntimeException: Update operation failed. Job aborted due to stage failure: Task 0 in stage 3.0 failed 4 times, most recent failure: Lost task 0.3 in stage 3.0 (TID 205, 192.168.2.140): java.lang.ArrayIndexOutOfBoundsException: 1

I have attached screen shot of log, executor log and CSV with this.
