-----------------------------------------------------------

The sql result of text fileformat would be right if i set hive.llap.io.enabled=false or set
hive.llap.io.encode.enabled=false.  Can someone explain why it is okay to close the tex cache?
 Is lllap cache only valid for orc?

> 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.
