kazuyukitanimura opened a new pull request #33690: URL: https://github.com/apache/spark/pull/33690
### What changes were proposed in this pull request? 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` This PR proposes to change the `_size` variable from `Int` to `Long` ### Why are the changes needed? Be cause the `size` method of `ChunkedByteBufferOutputStream` incorrectly returns a negative value when over 2GB data is written. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Passed existing tests ``` build/sbt "core/testOnly *ChunkedByteBufferOutputStreamSuite" ``` Also added a new unit test ``` build/sbt "core/testOnly *ChunkedByteBufferOutputStreamSuite – -z SPARK-36464" ``` -- This is an automated message from the Apache Git Service.
