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.
