[Spark-5068][SQL]Fix bug query data when path doesn't exist for HiveContext
This RP follow up PR #3907 & #3891 & #4356.
According to @marmbrus @liancheng 's comment,I try to use fs.globStatus
to retrieve all FileStatus objects under path(s), and then do the filtering
locally.
[1]. get path pathPattern, and put it into pathPatternSet.
(hdfs://cluster/user/demo/2016/08/12 -> hdfs://cluster/user/demo/*/*/*)
[2]. retrieve all FileStatus objects ,and cache them by undating
existPathSet.
[3]. do the filtering locally
[4]. if we have new pathPattern,do 1,2 step again. (external table maybe
have more than one partition pathPattern)
