--------------------------------
Summary: Pruner partition won't effective when udf exit in sql
predicates
Key: SPARK-8403
URL: https://issues.apache.org/jira/browse/SPARK-8403
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Hong Shen
When udf exit 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_2090000026 r where
r.cmd = 2 and (r.imp_date = 20150615 or and hour(r.itimestamp)>16)
{code}
When run on hive, it will only scan data in partition 20150615, but if run on
spark sql, it will scan the whole table fromt_dw_qqlive_2090000026.
