Dibyendu Bhattacharya b55e4b9a52 [SPARK-8080] [STREAMING] Receiver.store with Iterator does not give correct count at Spark UI
tdas  zsxwing this is the new PR for Spark-8080

I have merged https://github.com/apache/spark/pull/6659

Also to mention , for MEMORY_ONLY settings , when Block is not able to unrollSafely to memory if enough space is not there, BlockManager won't try to put the block and ReceivedBlockHandler will throw SparkException as it could not find the block id in PutResult. Thus number of records in block won't be counted if Block failed to unroll in memory. Which is fine.

For MEMORY_DISK settings , if BlockManager not able to unroll block to memory, block will still get deseralized to Disk. Same for WAL based store. So for those cases ( storage level = memory + disk )  number of records will be counted even though the block not able to unroll to memory.

thus I added the isFullyConsumed in the CountingIterator but have not used it as such case will never happen that block not fully consumed and ReceivedBlockHandler still get the block ID.

I have added few test cases to cover those block unrolling scenarios also.
