Li Bo created HDFS-7653: --------------------------- Summary: 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
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)
