Kai Zheng commented on HADOOP-11646: ------------------------------------ Thanks [~vinayrpet] for the codes ! > Erasure Coder API for encoding and decoding of block group > ---------------------------------------------------------- > > Key: HADOOP-11646 > URL: https://issues.apache.org/jira/browse/HADOOP-11646 > Project: Hadoop Common > Issue Type: Sub-task > Reporter: Kai Zheng > Assignee: Kai Zheng > Fix For: HDFS-7285 > > Attachments: HADOOP-11646-v4.patch, HDFS-7662-v1.patch, > HDFS-7662-v2.patch, HDFS-7662-v3.patch > > > This is to define ErasureCoder API for encoding and decoding of BlockGroup. > Given a BlockGroup, ErasureCoder extracts data chunks from the blocks and > leverages RawErasureCoder defined in HADOOP-11514 to perform concrete > encoding or decoding. Note this mainly focuses on the basic fundamental > aspects, and solves encoding, data blocks recovering and etc. Regarding > parity blocks recovering, as it involves multiple steps, HADOOP-11550 will > handle it. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
