CombineHiveInputFormat bug on tablesample
-----------------------------------------

                 Key: HIVE-1412
                 URL: https://issues.apache.org/jira/browse/HIVE-1412
             Project: Hadoop Hive
          Issue Type: Bug
            Reporter: Ning Zhang
            Assignee: Ning Zhang


CombineHiveInputFormat should combine all files inside one partition to form a split but should
not takes files cross partition boundary. This works for regular table and partitions since
all input paths are directory. However this breaks when the input is files (in which case
tablesample could be the use case). CombineHiveInputFormat should adjust to the case when
input could also be non-directories.
