> Re-write NNBench to use MapReduce
> ---------------------------------
>
> Key: HADOOP-2000
> URL: https://issues.apache.org/jira/browse/HADOOP-2000
> Project: Hadoop
> Issue Type: Test
> Components: test
> Affects Versions: 0.15.0
> Reporter: Mukund Madhugiri
> Assignee: Mukund Madhugiri
>
> The proposal is to re-write the NNBench benchmark/test to measure Namenode
> operations using MapReduce. Two buckets of measurements will be done:
> 1. Transactions per second
> 2. Average latency
> for these operations
> - Create and Close file
> - Open file
> - Rename file
> - Delete file
