Can multiple streaming apps use the same checkpoint directory?

[Ashic Mahtab]

Hi,
For client mode spark submits of applications, we can do the following:

def createStreamingContext() = {
...
 val sc = new SparkContext(conf)
 // Create a StreamingContext with a 1 second batch size
 val ssc = new StreamingContext(sc, Seconds(1))
}
...
val ssc = StreamingContext.getOrCreate(checkPointdir, createStreamingContext _)

If the driver goes down, and we restart it, it'll pick up where it left off. My 
question is if multiple streaming apps are submitted through the same machine, 
can the share the same check point directory, or does each have to have its own?

Thanks,
Ashic.
