[jira] [Updated] (SPARK-36464) Fix Underlying Size Variable
Initialization in ChunkedByteBufferOutputStream for Writing Over 2GB Data
[ https://issues.apache.org/jira/browse/SPARK-36464?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kazuyuki Tanimura updated SPARK-36464:
--------------------------------------
Description:
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`
