>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: fs/oss
>    Affects Versions: 3.0.3, 3.1.4, 2.10.2, 3.2.4, 3.3.4
>            Reporter: wujinhu
>            Assignee: wujinhu

> Recently, our customers raise a requirement: AliyunOSSBlockOutputStream 
> should support heap/off-heap buffer before uploading data to OSS.
> Currently, AliyunOSSBlockOutputStream buffers data in local directory before 
> uploading to OSS, it is not efficient compared to memory.
> Changes:
>  # Adds heap/off-heap buffers
>  # Adds limitation of memory used, and fallback to disk
