> 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.
