> Fix Underlying Size Variable Initialization in ChunkedByteBufferOutputStream for Writing Over 2GB Data
> ------------------------------------------------------------------------------------------------------
>
> Key: SPARK-36464
> URL: https://issues.apache.org/jira/browse/SPARK-36464
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.1.2
> Reporter: Kazuyuki Tanimura
> Priority: Major
>
> The `size` method of `ChunkedByteBufferOutputStream` returns a `Long` value; however, the underlying `_size` variable is initialized as `Int`.
> That causes an overflow and returns a negative size when over 2GB data is written into `ChunkedByteBufferOutputStream`
