> Hive support to read recursive directory by setting the property 'set mapred.input.dir.recursive=true', and Spark also support [such behavior|[https://stackoverflow.com/questions/42026043/how-to-recursively-read-hadoop-files-from-directory-using-spark]].
> For normal case, it won't happed for reading recursive directory. But it may happen in the following case:
> I have a paritioned table `fact_tz` with partition day/hour
> {code:java}
> CREATE TABLE fact_tz(x int) PARTITIONED BY (ds STRING, hr STRING) {code}
> Then I want to create an external table `fact_daily` refering to  `fact_tz`, but with a coarse-grained partition day. 
> {code:java}
> create external table fact_daily(x int) PARTITIONED BY (ds STRING) location 'fact_tz_localtion' ;
> ALTER TABLE fact_daily ADD PARTITION (ds='1') location 'fact_tz_localtion/ds=1'{code}
> But it wll throw exception "Not a file: fact_tz_localtion/ds=1" when try to query this table `fact_daily` for it's the first level of the origin partition and is actually a directory .
