> Key: DRILL-3688
> URL: https://issues.apache.org/jira/browse/DRILL-3688
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - Hive
> Affects Versions: 1.1.0
> Environment: 1.1
> Reporter: Hao Zhu
> Assignee: Arina Ielchiieva
> Fix For: 1.6.0
>
>
> Currently Drill does not honor the "skip.header.line.count" attribute of Hive
> table.
> It may cause some other format conversion issue.
> Reproduce:
> 1. Create a Hive table
> {code}
> create table h1db.testheader(col0 string)
> ROW FORMAT DELIMITED FIELDS TERMINATED BY '|'
> STORED AS TEXTFILE
> tblproperties("skip.header.line.count"="1");
> {code}
> 2. Prepare a sample data:
> {code}
> # cat test.data
> col0
> 2015-01-01
> {code}
> 3. Load sample data into Hive
> {code}
> LOAD DATA LOCAL INPATH '/xxx/test.data' OVERWRITE INTO TABLE h1db.testheader;
> {code}
> 4. Hive
> {code}
> hive> select * from h1db.testheader ;
> OK
> 2015-01-01
> Time taken: 0.254 seconds, Fetched: 1 row(s)
> {code}
> 5. Drill
> {code}
> > select * from hive.h1db.testheader ;
> +-------------+
> | col0 |
> +-------------+
> | col0 |
> | 2015-01-01 |
> +-------------+
> 2 rows selected (0.257 seconds)
> > select cast(col0 as date) from hive.h1db.testheader ;

> Also "skip.footer.line.count" should be taken into account.
> If "skip.header.line.count" or "skip.footer.line.count" has incorrect value
> in Hive, throw appropriate exception in Drill.
> Ex: Hive table property skip.header.line.count value 'someValue' is
> non-numeric
