Hi all, I start 5 small instances(1:NN, 1:BN, 3:DN) on Amazon EC2, and run my benchmark:
1. Create 1000 files to hdfs at a time.
2. The file size is 1kb.
3. Run 20 times.
Benchmark results(throughput):
only NN NN+BN
Min. 51.26127 39.51181
Max. 57.70650 43.12806
Avg. 53.97225 41.38930 (ops/sec)
NN+BN taken: 24.1802130 ms per file.
NN taken: 18.5422298 ms per file.
Are the results reasonable?
Thanks.
Shen
