Ability for HDFS client to write replicas in parallel -----------------------------------------------------
Key: HDFS-1783 URL: https://issues.apache.org/jira/browse/HDFS-1783 Project: Hadoop HDFS Issue Type: Improvement Components: hdfs client Reporter: dhruba borthakur Assignee: dhruba borthakur The current implementation of HDFS pipelines the writes to the three replicas. This introduces some latency for realtime latency sensitive applications. An alternate implementation that allows the client to write all replicas in parallel gives much better response times to these applications. -- This message is automatically generated by JIRA.
