Test queries: 

drop table if exists uniqdata;
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(36,36),double_column1 double, double_column2 double,integer_column1 int) stored as carbondata;
load data inpath 'hdfs://hacluster/user/prasanna/2000_UniqData.csv' into table uniqdata options('fileheader'='cust_id,cust_name,active_emui_version,dob,doj,bigint_column1,bigint_column2,decimal_column1,decimal_column2,double_column1,double_column2,integer_column1','bad_records_action'='force');

create datamap datamapuniq_b1 on table uniqdata(cust_name) as 'bloomfilter' PROPERTIES ('BLOOM_SIZE'='640000', 'BLOOM_FPP'='0.00001');
