Allen Wittenauer updated HDFS-1732: ----------------------------------- Fix Version/s: (was: 0.24.0) > 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: namenode > Affects Versions: 0.22.0 > Reporter: Matt Foley > Assignee: Matt Foley > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
