Stephane Maarek commented on SPARK-11374:
-----------------------------------------
I may add that more metadata isn't processed, namely TBLPROPERTIES
('serialization.null.format'='')
Also, another issue (may still be related to Spark not reading Hive Metadata or
not properly using Hive), but if you create a csv with the following (spaces
intended)
1, 2,3
4, 5,6
use Hive as this:
CREATE EXTERNAL TABLE `my_table`(
`c1` DECIMAL,
`c2` DECIMAL,
`c3` DECIMAL) ... etc
select * from my_table will return in Hive
1,2,3
4,5,6
But using a hive context, in Spark
1,null,3
4,null,6
> skip.header.line.count is ignored in HiveContext

> URL: https://issues.apache.org/jira/browse/SPARK-11374
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.5.1
> Reporter: Daniel Haviv
>
> csv table in Hive which is configured to skip the header row using
> TBLPROPERTIES("skip.header.line.count"="1").
> When querying from Hive the header row is not included in the data, but when
> running the same query via HiveContext I get the header row.
> "show create table " via the HiveContext confirms that it is aware of the
> setting.
