-----------------------------
Resolution: Duplicate
Duplicate of https://issues.apache.org/jira/browse/HIVE-1293
> no atomicity for a reader/writer for a job
> ------------------------------------------
>
> Key: HIVE-829
> URL: https://issues.apache.org/jira/browse/HIVE-829
> Project: Hadoop Hive
> Issue Type: New Feature
> Components: Query Processor
> Reporter: Namit Jain
>
> Hive currently does not provide any atomicity for a reader/writer.
> So, if a reader/writer is running concurrently, the reader may randomly die
> or even see partial results.
> Some kind of synchronization mechanisms (lease, lock in metastore/somewhere
> else) are needed to manage the above.
> This also applies to multiple writers (say multiple load into...)
