Yi Liu created HADOOP-11908: ------------------------------- Summary: Erasure coding: Should be able to encode part of parity blocks. Key: HADOOP-11908 URL: https://issues.apache.org/jira/browse/HADOOP-11908 Project: Hadoop Common Issue Type: Sub-task Reporter: Yi Liu Assignee: Yi Liu
{code} public void encode(ByteBuffer[] inputs, ByteBuffer[] outputs); {code} Currently when we do encode, the outputs are all parity blocks, we should be able to encode part of parity blocks. This is required when we do datanode striped block recovery, if one or more parity blocks are missed, we need to do encode to recovery them. Only encode part of parity blocks should be more efficient than all. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
