partition 20160501's dir didnt exits.
so when i use tez engine to run hive -e "select day,count(*) from a where xx=xx group by day"
hive throws FileNotFoundException.
but mr work.

repo eg:
CREATE EXTERNAL TABLE `a`(
  `a` string)
PARTITIONED BY ( 
  `l_date` string);

insert overwrite table a partition(l_date='2016-04-08') values (1),(2);
insert overwrite table a partition(l_date='2016-04-09') values (1),(2);
hadoop dfs -rm -r -f /warehouse/a/l_date=2016-04-09

select l_date,count(*) from a where a='1' group by l_date;
