Re: JDBC interpreter is not concurrent

[Prasad Wagle]

Hi Boris,

You can run concurrent queries by overriding the getScheduler function in
JDBCInterpreter to return ParallelScheduler like HiveInterpreter.

@jongyoul - should we change JDBCInterpreter. getScheduler to return
ParallelScheduler? It would also be nice to make maxConcurrency
configurable.

JDBCInterpreter:
  @Override
  public Scheduler getScheduler() {
    return SchedulerFactory.singleton().createOrGetFIFOScheduler(
        JDBCInterpreter.class.getName() + this.hashCode());
  }

HiveInterpreter:
  @Override
  public Scheduler getScheduler() {
    return SchedulerFactory.singleton().createOrGetParallelScheduler(
        HiveInterpreter.class.getName() + this.hashCode(), 10);
  }

Thanks,
Prasad
