Project: Hive
Issue Type: Bug

Hi all
I have a tableA partitioned by day/hour( insert overwrite table A
partiton(day,hour) select ...from table B where day =.. and hour =...) but
count(*) of table A and B is not equal occasionally (for example, hour =12).
when i rerun the job ( insert overwrite ..hour =12), the count(*) is
consistent. That means the bug cannot repeat.
I find the map output records is not equal to the reducer input records
