[jira] [Created] (SPARK-28019) Hive query gets empty result
Wu Tong created SPARK-28019:
-------------------------------
Summary: Hive query gets empty result
Key: SPARK-28019
URL: https://issues.apache.org/jira/browse/SPARK-28019
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.4.3
Reporter: Wu Tong
Hi,
I ran into the same issue as https://issues.apache.org/jira/browse/SPARK-26663
A hive table cannot be queried in spark 2.4.3. Spark 2.3.3 and 2.0.1 returns the correct result.
The table is created using the following script:
Hive1.2.1:
{code:java}
hive> create table recommend.test (`userid` BIGINT, `postid` BIGINT)
> PARTITIONED BY (`day` STRING)
> CLUSTERED BY (userid)
> INTO 32 BUCKETS
> 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'
> TBLPROPERTIES (
> 'orc.compress' = 'SNAPPY',
> 'transient_lastDdlTime' = '1515057885',
> 'NO_AUTO_COMPACTION' = 'true',
> 'transactional' = 'true'
> );
OK
Time taken: 0.344 seconds
hive> insert into recommend.test partition(day="day1") values(1, 2);
...
hive> select * from recommend.test;
OK
1 2 day1{code}
Spark 2.4.3:
{code:java}
scala> sql("select * from recommend.test").show()
19/06/12 15:36:09 WARN HiveMetastoreCatalog: Unable to infer schema for table recommend.test from file format ORC (inference mode: INFER_AND_SAVE). Using metastore schema.
