To prepare for it, this change uses ByteBuffer through the > codes in implementing striping position read. It will also fix avoiding > unnecessary data copying between striping read chunk buffers and decode input > buffers. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
