karen commented on HIVE-1242:
-----------------------------

The comment in the code include the followings:
// Since there is no easy way of knowing whether MAPREDUCE-1597 is present in 
the tree or not,
      // we use a configuration variable for the same

This is clearly misunderstanding. MAPREDUCE-1597 is a bug that was fixed for 
new  api (mapreduce package), while CombineHiveInputFormat is using old API 
(deprecated mapred package). CombineHiveInputFormat  does not properly works 
with any non-splittable compressed file, if that files is written over multiple 
hdfs partitions (same as CombineFileInputFormat from mapred package, while 
CombineFileInputFormat from new mapreduce package works beautifully).
Not sure why this issue is marked as closed.
