> 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
