Vinayakumar B commented on HDFS-8019:
-------------------------------------
bq. Might it be the configuration support a bit overkill? Could we start with
simple?
Anyway, configurations are not made mandatory. For starting we could define
optimal default values. As configurations would always help for testing without
need of code change everytime.
What you say?

> 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.
