Subject [jira] [Commented] (HDFS-8019) Erasure Coding: erasure coding chunk buffer allocation and management
Date Tue, 05 May 2015 18:08:01 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8019?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14528958#comment-14528958

Tsz Wo Nicholas Sze commented on HDFS-8019:
-------------------------------------------

Sure, using ByteArrayManager for now sounds good.

I think we don't need to have an interface for the moment unless the interface is trivial.
 But if the interface is trivial, adding it later is easy.

> 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.
