Lars Hofhansl commented on HDFS-1783: ------------------------------------- I see. That is a nice and simple change. Let's make a trunk patch. I'll do that as soon as I get a chance (within the next week or so). > 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.
