Description

I am trying to execute string function like: reverse, concat, lower, upper with the string/char column but it is giving error and when I am giving direct string value to it, it is working.

Create Table : CREATE TABLE uniqdata_char (CUST_ID int,CUST_NAME char(30),ACTIVE_EMUI_VERSION char(30), 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_char 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 : select Lower(cust_name) from uniqdata_char;

After running the query I am getting error.

But when I am running :
select Lower('TESTING') from uniqdata_char;
It is working fine.

I have attached CSV and Executor log with it.
