--------------------------------------
Assignee: Vaibhav Aggarwal
> Sampling fails after dynamic-partition insert into a bucketed s3n table
> -----------------------------------------------------------------------

> Key: HIVE-2150
> URL: https://issues.apache.org/jira/browse/HIVE-2150
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.7.0
> Reporter: Steven Wong
> Assignee: Vaibhav Aggarwal
>
> When using dynamic-partition insert and bucketing together on an s3n table,
> the insert does not create files for empty buckets. This will result in the
> following exception when running a sampling query that includes the empty
> buckets.
