> When multiple executors exist on a node, and the same block exists on both
> executors, with some in memory and some on disk.
> Probabilistically, the executor failed to obtain the block,throw Exception:
> java.lang.ArrayIndexOutofBoundsException: 0
> at
> org.apache.spark.broadcast.TorrentBroadcast.$anonfun$readBlocks$1(TorrentBroadcast.scala:183)
