-----------------------------------------
Summary: 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
The `size` method of `ChunkedByteBufferOutputStream` returns a `Long` value;
however, the underlying `_size` variable is initialized as `int`.
That causes an overflow and returns negative size when over 2GB data is written
into `ChunkedByteBufferOutputStream`
