> Streaming REST API Fails to Send Multiple Batches
> -------------------------------------------------
>
> Key: DRILL-7877
> URL: https://issues.apache.org/jira/browse/DRILL-7877
> Project: Apache Drill
> Issue Type: Bug
> Components: Client - HTTP
> Affects Versions: 1.19.0
> Reporter: Charles Givre
> Assignee: Charles Givre
> Priority: Blocker
> Fix For: 1.19.0
>
>
> The new streaming API appeared to have a minor bug for queries containing
> aggregates or anything complicated.
> When queries produced multiple batches, if you attempted to view these
> results, the first batch would only contain the schema in the first batch and
> no rows. The reader would then send additional batches, but no rows. This
> can be verified using Drill 1.19 and executing the following query:
> {code:sql}
> SELECT position_title, COUNT(*) as pc
> FROM cp.`employee.json`
> GROUP BY position_title
> {code}
