      Description

      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...)
