Subject [jira] Created: (HDFS-589) Change block write protocol to support pipeline recovery
Date Wed, 02 Sep 2009 18:42:32 GMT
Change block write protocol to support pipeline recovery

                 Key: HDFS-589
                 URL: https://issues.apache.org/jira/browse/HDFS-589
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: Append Branch
            Reporter: Hairong Kuang
            Assignee: Hairong Kuang
             Fix For: Append Branch

Current block write operation's header has the following fields:
blockId blockGS pipelineSize isRecovery clientName hasSource source #datanodesInDownStreamPipeline
I'd like to change the header to be
blockId blockGS pipelineSize clientName  flags blockMinLen blockMaxLen newGS hasSource source
#datanodesInDownStreamPipeline downstreamDatanodes

With this protocol change, pipeline recovery will be performed when a mew pipeline is set
