--------------------------------------
Summary: Improve S3AFastOutputStream memory management
Key: HADOOP-12387
URL: https://issues.apache.org/jira/browse/HADOOP-12387
Project: Hadoop Common
Issue Type: Sub-task
Reporter: Thomas Demoor
Assignee: Thomas Demoor
The use of ByteArrayOutputStream causes unexpected memory copies that causes
unintuitive memory usage for certain combinations of the configuration
parameters. Replacing it by more fine grained memory buffer management would
fix this, reduce memory usage and eliminate a memory copy.
