Enhance datanode to read data and checksum file in parallel -----------------------------------------------------------
Key: HDFS-1034 URL: https://issues.apache.org/jira/browse/HDFS-1034 Project: Hadoop HDFS Issue Type: Improvement Reporter: dhruba borthakur Assignee: dhruba borthakur In the current HDFS implementation, a read of a block issued to the datanode results in a disk access to the checksum file followed by a disk access to the checksum file. It would be nice to be able to do these two IOs in parallel to reduce read latency. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
