I forgot to update desc, already refine
if program go here `if (!putLevel.useMemory) {`, means put a disk level
block, or memory_and_disk level block which put in memory is failed and try to
put in disk(which `putLevel.useMemory` is false, and block `level.useMemory` is
true).
I not sure is reasonable to put twice in a short time.
```
if (!putLevel.useMemory) {
/*
* This RDD is not to be cached in memory, so we can just pass the
computed values as an
* iterator directly to the BlockManager rather than first fully
unrolling it in memory.
*/
updatedBlocks ++=
blockManager.putIterator(key, values, level, tellMaster = true,
effectiveStorageLevel)
blockManager.getLocal(key, !level.useMemory) match {
case Some(v) => v.data.asInstanceOf[Iterator[T]]
```
