      Here is my sql:

      tbllog_level_up and tbllog_gold is view which union by two tables, like this:
      create view tbllog_level_up as select * from tbllog_level_up_current union all select * tbllog_level_up_bak;

      When i run the sql on hive2.1 with mr engine,it is ok.
      But it throws the following exception with Tez0.8.4 engine:
