Introduction
...
The streaming benchmark consists of the following parts:
- Data Generation
The role of data generator is to generate a steady stream of data and send it to the Kafka cluster. Each record is labeled with the timestamp when it is generated.
- Kafka cluster
Kafka is a messaging system. Each streaming workload saves the data to its own topics.
- Test cluster
This could be a Spark cluster, Flink cluster, Storm cluster or Gearpump cluster. The streaming application (identity, repartition, wordcount, fixwindow) reads data from Kafka, processes the data and writes the results back to another topic in Kafka. Each record in the result is also labeled a timestamp.
- Metrics reader
It reads the result in Kafka and calculate the time difference(Record out time - Record in time) and generate the report.
Setup
...
- Python 2.x(>=2.6) is required.
Supported Hadoop version: Apache Hadoop 2.x, CDH5.x, HDP
Supported Spark version: 1.6.x, 2.0.x, 2.1.x, 2.2.x
Build HiBench according to build HiBench.
Start HDFS, Yarn in the cluster.
Setup Apache Kafka (0.8.2.2, scala version 2.10 is preferred): Start Kafka
Setup one of the streaming frameworks that you want to test.
Apache Spark (1.6.1, is preferred)
Apache Storm (1.0.1 is preferred).
Apache Flink (1.0.3 is prefered).
Apache Gearpump (0.8.1 is prefered)
We use Apache Spark 2.2.1 to streaming frameworks.
Hadoop Configuration
...
Hadoop is used to generate the input data of the workloads. Create and edit conf/hadoop.conf：
| Code Block | ||
|---|---|---|
| ||
cp conf/hadoop.conf.template conf/hadoop.conf |
Set the below properties properly:
| Property | Meaning |
|---|---|
| hibench.hadoop.home | /root/hadoop |
| hibench.hadoop.executable | ${hibench.hadoop.home}/bin/hadoop |
| hibench.hadoop.configure.dir | ${hibench.hadoop.home}/etc/hadoop |
| hibench.hdfs.master | hdfs://wls-arm-huawei01:9000 |
| hibench.hadoop.release | apache, cdh5, hdp |
Note: For CDH and HDP users, please update hibench.hadoop.executable, hibench.hadoop.configure.dir and hibench.hadoop.release properly.
The default value is for Apache release.
Kafka Configuration
...
Set the below Kafka properites in conf/hibench.conf and leave others as default.
| Property | Meaning |
|---|---|
| hibench.streambench.kafka.home | /root/kafka_2.10-0.8.2.2 |
| hibench.streambench.zkHost | wls-arm-huawei01:2181 |
| hibench.streambench.kafka.brokerList | wls-arm-huawei01:9092 |
| hibench.streambench.kafka.topicPartitions | Number of partitions of generated topic (default 20) |
Generate the data
...
Take workload identity as an example. genSeedDataset.sh generates the seed data on HDFS. dataGen.sh sends the data to Kafka.
| Code Block | ||
|---|---|---|
| ||
bin/workloads/streaming/identity/prepare/genSeedDataset.sh
bin/workloads/streaming/identity/prepare/dataGen.sh |
Run the streaming application
...
While the data are being sent to the Kafka, start the streaming application. Take Spark streaming as an example.
| Code Block | ||
|---|---|---|
| ||
bin/workloads/streaming/identity/spark/run.sh |
Generate the report
...
metrics_reader.sh is used to generate the report.
| Code Block | ||
|---|---|---|
| ||
bin/workloads/streaming/identity/common/metrics_reader.sh |
Debug for running Streaming bench
...
when running the streaming application:
| Code Block | ||
|---|---|---|
| ||
bin/workloads/streaming/identity/spark/run.sh |
There are some issues as follows:
streaming identity run into ERROR CheckpointWriter: Could not submit checkpoint task to the thread pool executor

The solutions:
- Turn off checkpointing :
| Code Block | ||
|---|---|---|
| ||
hibench.streambench.spark.checkpointPath false |
- Set "conf/spark.conf:hibench.streambench.spark.batchInterval" to a larger value
2. Process of generating data hangs
The solutions:
Modify conf/hibench.conf to make data-generating not in infinity mode:
| Code Block | ||
|---|---|---|
| ||
# Total round count of data send (default: -1 means infinity)
hibench.streambench.datagen.totalRounds -1 -> 512
# Number of total records that will be generated (default: -1 means infinity)
hibench.streambench.datagen.totalRecords -1 -> 1024 |
