Vinayakumar B updated HDFS-8019:
--------------------------------
Attachment: HDFS-8019-HDFS-7285-01.patch
Draft implementation of ByteBufferManager.
Almost same logic as ByteArrayManager,
except, this manages ByteBuffers and have option to specify whether to manage
native or heap buffers.
As of now separate managers need to be created for native and heap buffers.
This patch is just for initial review and feedback.

> As a task of HDFS-7344, this is to come up a chunk buffer pool allocating and
> managing coding chunk buffers, either based on on-heap or off-heap. Note this
> assumes some DataNodes are powerful in computing and performing EC coding
> work, so better to have this dedicated buffer pool and management.
