> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 3.2.0
> Reporter: Da Zhou
> Assignee: Da Zhou
> Priority: Major
> Fix For: 3.3.0

>
> In current AbfsOutPutStream, new temporary buffers always get allocated when
> uploading the data to server. These big chunk creates huge pressure on the
> GC, and in some extreme cases that GC doesn't happen in time(observed in some
> customer's env), it also lead to OutOfMemory issue easily.
> Hence we need to replace the current implementation with a bufferpool.
