Yuming Wang updated SPARK-18827:
--------------------------------
Attachment: NoSuchElementException4722.gif
> Cann't read broadcast if broadcast blocks are stored on-disk
> ------------------------------------------------------------
>
> Key: SPARK-18827
> URL: https://issues.apache.org/jira/browse/SPARK-18827
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.0.1, 2.0.2, 2.1.0
> Reporter: Yuming Wang
> Attachments: NoSuchElementException4722.gif
>
>
> How to reproduce it:
> {code:java}
> test("Cache broadcast to disk") {
> val conf = new SparkConf()
> .setAppName("Cache broadcast to disk")
> .setMaster("local")
> .set("spark.memory.useLegacyMode", "true")
> .set("spark.storage.memoryFraction", "0.0")
> sc = new SparkContext(conf)
> val list = List[Int](1, 2, 3, 4)
> val broadcast = sc.broadcast(list)
> assert(broadcast.value.sum === 10)
> }
> {code}
> {{NoSuchElementException}} will throw since SPARK-17503 if a broadcast cannot
> cache in memory. The reason is that that change cannot cover
> {{!unrolled.hasNext}} in {{next()}} function.
