Hive creates partitions with leading zero

Question

I'm using hive Hive 1.0.0-amzn-3, In this version hive creates partitions dynamically, it ignores the type of the partition field type. In my case it creates partitions with leading zero, while field type is Integer.

day_ts=16/hour_ts=05

When I've upgraded hive to Hive 2.1.1-amzn-0 the behavior changed, the new partitions aligned with the type of the field and leading zero removed.

day_ts=16/hour_ts=4

Appreciate any lead to how allow hive 2.1 to keep the leading zero. thanks.

Here is an example

CREATE EXTERNAL TABLE `partitions_hell`(
  `a` string COMMENT,
  `b` string COMMENT  
  )
PARTITIONED BY (
  `day_ts` bigint,
  `hour_ts` int)
ROW FORMAT SERDE
  'org.apache.hadoop.hive.ql.io.orc.OrcSerde'
STORED AS INPUTFORMAT
  'org.apache.hadoop.hive.ql.io.orc.OrcInputFormat'
OUTPUTFORMAT
  'org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat'

LOCATION
  's3://xarkadiy-snbx/partitions_hell'

TBLPROPERTIES (
  'orc.compress'='SNAPPY'
)

Run Following query in hive 1.0.0

INSERT INTO TABLE partitions_hell_arkadiy partition(day_ts=16, hour_ts=05)
SELECT '11',
       'rwr'
FROM partitions_hell_arkadiy

Run Following query in hive 2.1.0

INSERT INTO TABLE partitions_hell_arkadiy partition(day_ts=16, hour_ts=04)
select '131', 'rw33rr'
from  partitions_hell_arkadiy

Result:

hive> show partitions default.partitions_hell
    > ;
OK
