Konstantin Shvachko commented on HDFS-9436: ------------------------------------------- Hey Mingliang, I thought you will increase the default only for {{BlockReportStats}}, but you made the change in {{OperationStatsBase}}, which changes the default for all other ops as well. I don't know if it is needed. Was it intentional? > Make NNThroughputBenchmark$BlockReportStats run with 10 datanodes by default > ---------------------------------------------------------------------------- > > Key: HDFS-9436 > URL: https://issues.apache.org/jira/browse/HDFS-9436 > Project: Hadoop HDFS > Issue Type: Improvement > Components: test > Reporter: Mingliang Liu > Assignee: Mingliang Liu > Priority: Minor > Fix For: 2.8.0 > > Attachments: HDFS-9436.000.patch > > > This is a follow-up of [HDFS-9379]. > Though for actual benchmarking the defaults are rarely used, it would be good > to change the default for {{numThreads}} as a >=10 value and may be > {{numOpsRequired}} in {{BlockReportStats}} just to make sure the condition in > [HDFS-9379] is tested in the future. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
