Ning Zhang commented on HIVE-1510:
----------------------------------
In HiveFileFormatUtils, removing scheme and authorities from the URI and only
retain the path part may cause problem when the URI is har:// rather than
hdfs://. This is one of the bugs that Paul fixed in hadoop for HAR to be able
to work with CHIF.
As a general comment, is it easier to just modify the pathToPartitionInfo to
add a Path.SEPARATER at the end? You don't need to introduce the recursive
checking and still can use the prefix matching.
> HiveCombineInputFormat should not use prefix matching to find the
> partitionDesc for a given path
