Sorry for the inconvenience; I've added some detailed description, [~srowen] 
would you mind reopen it? Thanks. :-)

> Currently in Spark Streaming, a Receiver stores the received data into some 
> BlockManager and then later the data will be used by a BlockRDD. If this 
> BlockManager were to lost because of some failure, then this BlockRDD would 
> throw a SparkException saying "Could not compute split, block not found".
> In most cases this is the right thing to do. However, in a streaming scenario 
> where it can tolerant small pieces of data loss, maybe just move on silently 
> -- instead of throwing an exception -- is more preferable.
> This issue proposes to add such an "spark.streaming.ignoreBlockNotFound" 
> option, which defaults to false, to tell whether to throw an exception or 
> just move on when a block is not found.

[~proflin] there's no detail here. It doesn't sound like something that should 
be optionally ignored. I'd have to close this unless you can make a case for 
this, or at least describe it.
