Hong Shen updated SPARK-8403:
-
Description:
When partition field and fieldSchema exist in sql predicates, pruner partition
won't effective.
Here is the sql,
{code}
select r.uin,r.vid,r.ctype,r.bakstr2,r.cmd from t_dw_qqlive_209026 r where
r.cmd = 2 and (r.imp_date = 20150615 or and hour(r.itimestamp)16)
{code}
Table t_dw_qqlive_209026 is partition by imp_date, itimestamp is a
fieldSchema in t_dw_qqlive_209026.
When run on hive, it will only scan data in partition 20150615, but if run on
spark sql, it will scan the whole table t_dw_qqlive_209026.
