> Concurrent Queries Failed Unexpectedly
> --------------------------------------
>
> Key: DRILL-3833
> URL: https://issues.apache.org/jira/browse/DRILL-3833
> Project: Apache Drill
> Issue Type: Bug
> Components: Client - JDBC, Execution - RPC
> Affects Versions: 1.1.0, 1.2.0
> Environment: CentOS release 6.6 (Final)
> Hadoop-2.7.1
> Drill-1.1.0
> Single drillbit on single zookeeper
> Reporter: Yiyi Hu
> Labels: hdfs, jdbc, rpc
> Fix For: 1.7.0
>
> Attachments: drillbit.log

> Concurrent queries with a relatively large LIMIT size *failed*, where the
> failure occurred randomly.
> To reproduce:
> - Test data: a JSON file test.json (at least 10,000,000 records, two fields
> id<int>, title<string>);
> - Submit 5 queries with 5 separate threads using jdbc, where the query is:
> {panel}
> SELECT id, title FROM dfs.`test.json` LIMIT 10000000;
> {panel}
> - The error message in drillbit.log:
> {noformat}

> - Related to DRILL-3763. But the differences are, the queries were submitted
> through jdbc directly, and there was no external interruption in this case.
