>             Project: Apache Tez
>          Issue Type: Bug
>    Affects Versions: 0.8.4
>         Environment: HiveServer2 1.2.1 Local mode + Tez

> When running parallel queries (simultaneous connections by two beeline clients to HS2), I get the following exception (full debug attached), interestingly running the queries one after the other completes without any problem. The partition location and actual files seem to get mixed up across the DAGS
>  
> The setup is Hive (1.2.1) and Tez (0.8.4) running in local mode.
