      Description

      I found that llap execution occurs different result using textfile fileformat and same sql when i test llap with TPCDS textfile data. And the orc fileformat is ok. The attachment(llap_tpcds_text_500_query53.sql) are TPCDS query53.sql execution results with data tpcds_text_500(500GB textfile), and you can find the results is different every time. The attachment (tez_tpcds_text_500_query53.sql) is the tez container execution mode and it is the right result, which is same as llap with orc textfile fileformat.
