------------------------------------
Summary: Partition length number overflow in
`PartitionWriterStream`
Key: SPARK-32658
URL: https://issues.apache.org/jira/browse/SPARK-32658
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 3.0.0
Reporter: Xingbo Jiang
A Spark user reported `FetchFailedException: Stream is corrupted` error when
they upgraded their workload to 3.0. The issue happens when the shuffle output
data size from a single task is very large (~5GB). The issue is introduced by
https://github.com/apache/spark/commit/abef84a868e9e15f346eea315bbab0ec8ac8e389
, the `PartitionWriterStream` defined the partition length to be an int value,
while it should be a long value.
