Qiang Yang updated SPARK-43221:
-------------------------------
Description:
Spark on Yarn Cluster
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)
Next, I will replay the process of the problem occurring:
step 1:
The executor requests the driver to obtain block
information(locationsAndStatusOption). The input parameters are BlockId and the
host of its own node. Please note that it does not carry port information
step 2:
