Hi,
I'm trying to benchmark Flink without Kafka as mentioned in this post (
http://data-artisans.com/extending-the-yahoo-streaming-benchmark/). After
running flink.benchmark.state.AdvertisingTopologyFlinkState with
user.local.event.generator in localConf.yaml set to 1, I ran
flink.benchmark.utils.AnalyzeTool giving flink-1.0.1/log/flink-[
username]-jobmanager-0-[servername].log as a command-line argument. I got
the following output and it does not have the information about the latency.
================= Latency (0 reports ) =====================
================= Throughput (1 reports ) =====================
====== null (entries: 10150)=======
Mean throughput 639078.5018497099
Exception in thread "main" java.lang.IndexOutOfBoundsException: toIndex = 2
at java.util.ArrayList.subListRangeCheck(ArrayList.java:962)
at java.util.ArrayList.subList(ArrayList.java:954)
at flink.benchmark.utils.AnalyzeTool.main(AnalyzeTool.java:133)
Reading the code in AnalyzeTool.java, I found that it's looking for lines
that include "Latency" in the log file, but apparently it's not finding
any. I tried grepping the log file, and couldn't find any either. I have
one server that runs both JobManager and Task Manager and another server
that runs Redis, and they are connected through a network with each other.
I think I have to do something to read the data stored in Redis before
running AnalyzeTool, but can't figure out what. Does anyone know how to get
the latency information?
Thanks,
Eric
