Parent: HDFS-2126
> Enhance NNThroughputBenchmark to observe scale-dependent changes in IBR
> processing
> ----------------------------------------------------------------------------------
>
> Key: HDFS-1732
> URL: https://issues.apache.org/jira/browse/HDFS-1732
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: name-node
> Affects Versions: 0.22.0
> Reporter: Matt Foley
> Assignee: Matt Foley
> Fix For: 0.23.0
>
> Attachments: IBRBenchmark_apachetrunk_v8.patch,
> IBRBenchmark_apachetrunk_v9.patch
>
>
> Rework NNThroughputBenchmark to provide more detailed info about Initial
> Block Report (IBR) processing time, as a function of number of nodes, number
> of unique blocks, and total number of replicas.
> Allow both direct local communication and remote and local RPC, so we can see
> how much impact RPC overhead has on IBR processing time.
> Also plug some holes in performance-specific logging of Block Report
> processing, so that consistent and complete data are logged from both
> Namenode and Datanode.
