    do you know what was the behavior before? Will we propagate the exception all the way up and kill the executor?

    I think `growAndRehash` always thrown `SparkOutOfMemoryError`. catch `SparkOutOfMemoryError` or `OutOfMemoryError` will make `canGrowArray = false`.  please correct if i understand something wrong. thanks.

    @cloud-fan, I think not kill executor.  the memory allocate fails, and the caller is notified to perform other operations. for example, HashAggregateExec will carry out spill the map and fallback to sort-based.
    please correct if i understand something wrong.  thanks.
