Hyukjin Kwon updated SPARK-27595:
---------------------------------
Description:
{code}
create external table unique_keys (
key string
,locator_id string
, create_date string
, sequence int
)
partitioned by (source string)
stored as orc location '/user/hive/warehouse/reservation.db/unique_keys';
{code}
{{/user/hive/warehouse/reservation.db/unique_keys}} contains data like below:
{code}
/user/hive/warehouse/reservation.db/unique_keys/source=6S
/user/hive/warehouse/reservation.db/unique_keys/source=7F
/user/hive/warehouse/reservation.db/unique_keys/source=7H
/user/hive/warehouse/reservation.db/unique_keys/source=8D
{code}
If I try to read orc files through Spark,
{code}
val masterDF =
hiveContext.read.orc("/user/hive/warehouse/reservation.db/unique_keys")
{code}
source value getting changed to *7.0 and 8.0* for 7F and 8D respectively.
