[HDFS-dev] [jira] [Created] (HDFS-1783) Ability for HDFS client to write replicas in parallel

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.
