> Key: HIVE-5747
> URL: https://issues.apache.org/jira/browse/HIVE-5747
> Project: Hive
> Issue Type: Improvement
> Components: HCatalog
> Affects Versions: 0.10.0
> Reporter: Rekha Joshi
> Priority: Minor
>
> Creating hcatalog table using creating tables and alter table add partition
> is most used approach.However at times the incoming files can come with
> header row/column names.
> In such cases it would be good feature to be able skip header/rows.
> Suggestions below:
> hcat "alter table rawevents add partition (ds='20100819') location
> 'hdfs://data/rawevents/20100819/data' -skip header"
> hcat "alter table rawevents add partition (ds='20100819') location
> 'hdfs://data/rawevents/20100819/data' -skip [n]"
> hcat "alter table rawevents add partition (ds='20100819') location
> 'hdfs://data/rawevents/20100819/data'" -DskipRow=1
> -- can choose with bounded array (rows) for selecting rows for table
> hcat "alter table rawevents add partition (ds='20100819') location
> 'hdfs://data/rawevents/20100819/data' -rows[2:]" // from first row till all
> hcat "alter table rawevents add partition (ds='20100819') location
> 'hdfs://data/rawevents/20100819/data' -rows[2:100]" // from first row till
> 100 rows
> Correct place for this feature in hive or hcat?or with -D can be handled in
> hcat?
> Thanks
