> Load command:
> LOAD DATA INPATH 'hdfs://localhost:54311/2000_UniqData.csv'
> into table uniqdata_string_new partition(active_emui_version='abc') 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');
> LOAD DATA INPATH 'hdfs://localhost:54311/2000_UniqData.csv'

> active_emui_version=abc
> active_emui_version=xyz

> alter table uniqdata_string_new drop partition(active_emui_version='xyz');
> show partitions uniqdata_string_new;
> +---------------------------+-+
> |partition|
