Li Bo resolved HDFS-7653. ------------------------- Resolution: Won't Fix Release Note: The design and implementation have changed a lot after this issue created. Due to the complexity and difference of client and datanode side read/write, we'll not solve this issue at current stage. > Block Readers and Writers used in both client side and datanode side > -------------------------------------------------------------------- > > Key: HDFS-7653 > URL: https://issues.apache.org/jira/browse/HDFS-7653 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Li Bo > Assignee: Li Bo > Attachments: BlockReadersWriters.patch > > > There're a lot of block read/write operations in HDFS-EC, for example, when > client writes a file in striping layout, client has to write several blocks > to several different datanodes; if a datanode wants to do an > encoding/decoding task, it has to read several blocks from itself and other > datanodes, and writes one or more blocks to itself or other datanodes. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
