zhangbutao commented on HIVE-21123:
-----------------------------------
The sql result of text fileformat would be right if i set
hive.llap.io.enabled=false. Can someone explain why it is okay to close the
cache? Is lllap cache only valid for orc?
> LLAP : same sql and TPCDS data occurs different results using textfile
> fileformat

> 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.
