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

language	cpp

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

language	bash

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

language	bash

bin/workloads/streaming/identity/spark/run.sh

...

Generate the report

...

metrics_reader.sh is used to generate the report.

Code Block

language	bash

bin/workloads/streaming/identity/common/metrics_reader.sh

...

Debug for running Streaming bench

...

when running the streaming application:

Code Block

language	bash

bin/workloads/streaming/identity/spark/run.sh

Then 2 kinds error occursThere are some issues as follows:

streaming identity run into ERROR CheckpointWriter: Could not submit checkpoint task to the thread pool executor

Code Block

language	bash

The

...

solutions:

Turn off checkpointing

...

:

Code Block

language	bash

hibench.streambench.spark.checkpointPath false

Set "conf/spark.conf:hibench.streambench.spark.batchInterval" to a larger value

...

2. process Hangs when generating data Process of generating data hangs

The

...

solutions:

Modify conf/hibench.conf to make data-generating not in infinity mode:
